Question

What is the volume of the cone?

Answer 1

42.417 cm³

Step-by-step explanation:

The formula to find the volume of a cone is :

V =
`(1)/(3)` × π r² h

Here,

r ⇒ radius ⇒ 3 cm

h ⇒ height ⇒ 4.5 cm

Let us find it now.

V =
`(1)/(3)` × π r² h

V =
`(1)/(3)` × π × 3 × 3 × 4.5

V =
`(1)/(3)` × π × 9 × 4.5

V =
`(1)/(3)` × π × 9 × 4.5

V =
`(1)/(3)` × π × 40.5

V =
`(1)/(3)` × 3.142 × 40.5

V =
`(1)/(3)` × 127.251

V = 42.417 cm³
