Question

The volume of a cone is 62.8 cubic inches. The height of the cone is 15 inches. What is the radius of the cone, rounded to the nearest inch? Use π = 3.14.

A. 2in.
B. 4in.
C. 8in.
D. 9in.

Answer 1

We know that, The volume of a cone V= (1/3)*Pi*r^2*h
here, volume is V= 62.8 cubic inches, Pi π = 3.14, The height of the cone h is 15 inches.
Make Radius r^2 as subject of equation in doing so, u get
\[r=\sqrt{(3V)/(\pi*h)}\] find r vaue

Answer 2

So the answer is 8?
