u need the radius and the height

In order to find the volume of a cylinder, you need to have the radius and height. Based on information I now, the formula for the volume of a cylinder is V = πr^2 • h, so you need to have the height of the entire cylinder and radius of the circle in the cylinder to find the volume as Pi is a set number.

There can NOT be 15 pieces of candy in the bag, therefore answer choice B is correct.  From my knowledge of part:part and part:whole ratios as well as equivalent ratios, I know that if the ratio of the two types of candy in the bag is 3:4, then there are 7 pieces of candy in a "group."  15 is NOT a multiple of 7, therefor it cannot be the amount of candy in the bag.

The answer is (b). Since know that x = 3/4y, the total can be represented as follows (T = x+ y) or (T = 3/4y + y) or (T = 7/4y). This equation can be repurposed as y = 4/7T. Substituting each of the totals that we are given produces a value of y and by extension x that have a ratio of 3:4.

The radius and the height of the cylinder is the minimum needed to find volume. Volume represents the space inside the cylinder which includes a circle being repeated by its height amount of times. Therefore, the area of the circle, which uses the radius, and the height is the only thing that is needed.

Problem two is asking for the minimum requirements to solving the volume of a cylinder. Knowing the formula for volume of a cylinder, you would need the height of the cylinder and the radius or diameter of the circle at the base.

The volume of a cylinder is pi*r-squared*height. The minimum information needed is the radius and the height of a volume.

The volume of a cylinder is pi*r-squared*height. The minimum information needed is the radius and the height of a volume.

The minimum amount of information needed is the radius of the base and the height of the cylinder. According to the volume formula for a cylinder, V=pi*r^2*h, the only two variables needed are r (the radius) and h (the height).

The minimum information to find the volume of a cylinder is knowing the radius and the height.  Using my knowledge of the volume of a cylinder equation: V=pi*r^2*h, I can conclude that you must input information for the radius and the height in order to define the Volume of a cylinder.

In order to find the volume of a cylinder, you would need the radius of the base and the height of the cylinder. The volume formula is Pi*r^2*h. Therefore, we need to know both the radius of the base and the height of the cylinder.

The ratio is 3:4. So the sum of the two numbers must be a multiple of 7. This is because 3x + 4x = 7x where x = 1, 2, 3,.... As a result, the answer is B (i.e. 15). 15 is the only answer that is not a multiple of 7.

The total number of candies that cannot be in the bag is [b], 15. From previous knowledge of equivalent ratios, I need to multiply (or in some cases divide) both parts of the ratio by the same number. I'll need to add the two numbers of the each individual ratio together to find the total number of candies represent by each ratio. I can also identify that each total can be a multiple of the total number of candies of the first ratio, which is 7. The only answer that is not a multiple of 7 is 15.

The answer to the probm is B. 15.  I have learned that ratios like 3:4 have equivalent ratios that can be found by both terms by the same number.  For example, if both are multiplied by two you get the equivalent ratio of 6:8, which has a sum of 14 (A).  You can continue this process and find 9:12, 12:16 ( C ) and 15:20 (D).  There is no way of gettingthe sum of 15, while maintaining the 3:4 ratio, so that is why B is the solution this problem.

At minimum you need the height of the cylinder and the radius of the base of the cylinder in order to find its volume. From my notes on page 38 of my notebook, I know that volume is the interior space of the cylinder so we would need to know how large (area) the base is, which is a circle. To find that area we only need the radius of that circle. Then we need to know how many of those base circles would make up the cylinder which would be the height of the cylinder. Therefore we would need the radius of the base of the cylinder and the height of the cylinder.

1. We are trying to exclude impossible answer options for the total number of candies in a bag that contains two types of candies in a ratio of 3:4.
2. For a ratio of 3:4, the total number n of candies must satisfy the condition (3+4)x = n with x being a whole number; the total number of candies must be a multiple of 7.
3. Hence, answer choice B (15) can not be a valid answer number of candies in the bag - choice B is the correct answer.

The minimum information you need is the height and the radius of the cylinder. From the notes, I know that the formula for a cylinder's volume is V = pi r^2h. The only two variables that need to be inputted into the formula are radius and height. You could be given several details about the cylinder (circumference, SA, ect.) but they are not in the formula thus are unnecessary info.

The total number of candies in the bag cannot be B 15. Because the ratio has to be 3:4, I know that the total number of candy 1 over the total number of candy 2 must reduce to 3/4. Therefore, there will be some constant, x, such that 3x + 4x = total number of candies. Therefore, 7x = the total number of candies so the answer must be a multiple of 7. The answer choice of B (15) is the only answer that is not a multiple of 7.

Inquire: 3+4 equals 7 candies total
Introduce Evidence: 14, 15, 28, 35 and we are looking for multiples of 7
Interpret: 15 is not a multiple of 7

The product of x2 and x8 is answer [c], x10. From my notes on April 3, I know that when multiplying powers, if the bases are the same, I can add the exponents. x2 has a base x as x8 has a base of x; therefore, I can add the exponents. Adding them gives 2+8, which is 10. So the answer is [c]: x10.
