Answer 1

Radius, r = 6 inches

Explanation:

We have,

Volume of a cone is 565.2 cubic inches

Height of the cone is 15 inches

It is required to find the radius of the cone. Volume of a cone is given by :

`V=(1)/(3)\pi r^2 h`

r is radius of cone

`r=\sqrt{(3V)/(\pi h)} \\\\r=\sqrt{(3* 565.2)/(3.14* 15)} \\\\r=6\ \text{inch}`

So, the radius of the cone is 6 inches. The correct option is (b).
