Length = 9.9 inches
Width = 3.4 inches
Height = 1.6 inches

Volume of rectangular prism =

Area for Circle: pi(r^2) _____  3.14(1^2)= 3.14
Volume for Circle: area(height) ______  3.14(5)= 15.71 inches

Volume= 16 inches ^3

Estimated Volume:

Radius = 1 in
Height = 2.25 in

Area of Base (Circle)= pi x r^2
= (pi)(1)^2
= 3.14 in^2

Volume = area x h
= (3.14) x (2.25)
= 7.065 in

# data[].attributes.body
Estimated volume = 10.99 in^3

Radius = 1 in
Height = 3.5 in

Volume = pi x r^2 x h
= pi x (1)^2 x 3.5
= 10.99

Estimated volume of cylinder:
Height: 10in
Diameter: 2.5in
Area of circular base: pi(r)^2 = pi(1.25)^2 = 4.9
Volume of cylinder: area x height = 4.9 x 10 = 49in^3

# data[].attributes.body
estimated volume: 268.08 in^3
found the diameter, 8 in, so radius is 4 in and the volume formula is 4/3*pi*r^3

Area of a circle: pi r ^2
Area: pi(2)^2 = pi4 = 12.57
Volume of a cylinder: area x H
12.57 x 12 = 150.8 in^3

Estimated volume is 779.31 cubic cm.
Find the area of the circular base by pi(r)^2, where the r = 5.25 cm.
pi(5.25)^2 = 86.55 square cm
Then multiply by the area of the base by the height of the cylinder, where h = 9 cm; pi(r)^2 * h.
pi(5.25)^2 * 9 = 779.31 cubic cm

# data[].attributes.body
Estimated Volume: 12.56 in^3
(r= 1 in., h=4 in.)
Using the are of the base (pi(r)^2=pi(1 in)^2=pi * 4 in (height)= 12.56 in^2

Estimated Volume: 61.91in^3
Using the area of the base (pi*r^2=pi*1.55in^2=7.55in^2) * the height (8.2in). So 7.55in^2*8.2in=61.91in^3.

Estimated Volume is  56.56 in^3 using area of the circular base (r= 1.50 in., h= 8.00 in.)
area= pi(r^2)  = 3.14(2.25) = 7.07 in^2 then multiplied by the height
--> 7.07in^2(8.00 in) = 56.56in^3

Estimated volume is 154.91 cu. mm. using area of the circular base * height of the bottle. r = 2.25 mm, h = 9.75 mm
(π r² * h = 3.14 * 5.06 mm² *
9.75 mm = 154.91 mm³)

# data[].attributes.body
Estimated Volume is 1186.92 cu in. Using the area of the circular base (pi*r squared=3.14*3 in squared=28.26 in squared) multiplied by the height of the roller (base area*h=28.26in*42in=1186.92 cu in.)
