Find the volume of a cone of radius 3.5cm and vertical height 12cm. [Take π = 22/7]
Answer Details
The formula for the volume of a cone is V = 1/3 πr^2h, where r is the radius of the base and h is the height of the cone.
Substituting the given values into the formula:
V = 1/3 × 22/7 × (3.5cm)^2 × 12cm
= 1/3 × 22/7 × 12.25cm^2 × 12cm
= 1/3 × 22/7 × 147cm^3
= 22/7 × 49cm^3
= 154cm^3
Therefore, the volume of the cone is 154cm^3.
The answer is (d) 154cm3.
