What is the formula for the volume of a cone? The formula for the volume of a cone is ⅓ 𝜋r2h cubic units, where r is the radius of the circular base and h is the height of the cone.

Given data
Base radius (r) of the cone = 5.6 cm
Slant height (l) of the cone = 9 cm, as shown in figure.
As we know that the curved surface area (C.S.A) of the cone is given as πrl unit square.
Therefore substitute all the values in the above equation we have,
⇒C.S.A=πrl=227(5.6)(9) cm2 [∵π=227].
Now simplify the above equation we have,
⇒C.S.A=227(5.6)(9) = 22(0.8)(9) = 158.4 cm2
