What is the volume of the sphere shown below with a radius of 9

Sati [7]

Answer:

972π or 3052.08 if π=3.14(remember to label the answer with your units)

Step-by-step explanation:

The formula for the volume of a sphere is $\frac{4}{3}\\$ π $r^{3}$ . So, just plug the radius into the formula. $r^{3}$ <em> </em>in this case is $9^{3}$ which is 729. For, $\frac{4}{3}$ ×729, the 3 and 729 cancel out to create 4×243 which is 972. Just add π to this and you get 972π. If π is 3.14 just multiple 972 and 3.14 to get 3052.08.
