PLEASE HELP!

Answer 1

To find the approximate volume that was released you will find the volume of the sphere before and after the water was released and subtract them.  Use the formula for finding the volume of a sphere to do this.

Before:  

V=4/3 x pi x r^3
    4/3 x 3.14 x 4.5^3
V = 381.51 cubic inches

After:

V=4/3 x pi x r^3
    4/3 x 3.14 x 3.6^3
V = 195.33 cubic inches

381.51 - 195.33 = 186.18 cubic inches


The answer is choice B.
