If the numerical values of the area of the base and the volume of a right circular cone of radius 4cm be equal , then the slant height of the cone is

A

3cm

B

4cm

C

5cm

D

6cm

Text Solution

Verified by Experts

Let the height of the cone be h cm .
As per questions , `(1)/(3)pi.4^2.h=pi.4^2rArr h=3`.
`therefore` the slant height of the cone ` =sqrt(4^2+3^2)cm=5cm`.
`therefore` (c) is correct.
