Answer:

V = 125 pi cm^3

V = 392.6990817 cm^3

Step-by-step explanation:

Volume of a cone = 1/3 pi r^2 h

The diameter is two times the radius

d =2r

10 = 2r

10/2 = 2r/2

5 =r

                    V         = 1/3 * pi * (5)^2 *15

                                = 1/3 * pi *25 *15

                                =125* pi

Approximate pi as 3.14

                     V = 392.6990817 cm^3
