Question

FIND THE VOLUME OF A CONE 0F DIAMETER 14M AND HEIGHT 21CM. (TAKE = 3 )

Answer 1

343π

Explanation:

To find the volume of a cone, we have to use this formula

`(1)/(3)` × π × r² × h

Where 'r' is the radius and 'h' is the height

Let's start putting in the value's

We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7

`(1)/(3)` × π × r² × h

`(1)/(3)` × π × 7² × 21

→ Simplify the expression

`(1)/(3)` × π × 49 × 21

→ Simplify it further

343π
