Question

The diameter, D, of a sphere is 15 . Calculate the sphere's volume, V . Use the value 3.14 for pi , and round your answer to the nearest tenth.

Answer 1

Answer:

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. )

Answer 2

Answer:

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
