Audrey · Answer 1

V = 1767.2

Step-by-step explanation:

V=4/3πr3

(I'm pretty sure I rounded that right. If not it's 1767.15 before rounding.)

Jax · Answer 2

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3) πr³, were r is the radius.

If we are told only that the diameter is 15, we must find the radius before applying the above formula. The radius is r = 15/2.

The formula for the volume of a sphere is V = (4/3) πr³ yields

V = (4/3) (3.14) (15/2) ^3, or

= 1,766.3 cubic units
