Question

The volume of a cone is 1570cm3 if its base area is 314cm2 then its height is ?

Answer 1

Answer: 15 cm

Step-by-step explanation:

Given,

Volume of cone = 1570 cm^3

Base area = 314 cm^2

To find : Height

Volume = 1/3 *pi*r^2 * height

But, pi*r^2 = base area of cone

Volume = 1/3 * base area * height

Height = 3*Volume/Base area

            = 3*1570/314 = 15 cm
