Question

If a right circular cone has radius 4 cm and slant height 5 cm then what is its volume?

Answer 1

volume of cone =25.142 cm^3

Answer 2

The volume of cone is 50.24 cubic cm

Step-by-step explanation:

Radius of cone r = 4 cm

Slant height of cone l = 5 cm

So, $l^2= r^2 +h^2$

$5^2=4^2+h^2$

$\sqrt{5^2-4^2}=h$

3 cm = h

Volume of cone = $\frac{1}{3} \pi r^2 h$

Volume of cone = $\frac{1}{3} \times 3.14 \times 4^2 \times 3$

Volume of cone = $50.24 cm^3$

Hence The volume of cone is 50.24 cubic cm
