The radius of the base of a cone is 5 cm while its height is 12 cm. Find the volume of this cone.
(Take π = 3.14)
We have

Given: radius of the cone, r = 5 cm
Height of the cone, h = 12 cm
We know, volume of cone is given by
Volume = 1/3 πr2h
Substituting given values in the above equation, we get
Volume = 1/3 × 3.14 × 52 × 12
⇒ Volume = 942/3 = 314
Thus, volume of cone is 314 cm3.
