If the sphere shown above has a radius of 6 units, then what is the approximate volume of the sphere? A. 1,130.4 cubic units B.

alexandr1967 [171]

Volume of a sphere is calculated with V=(4/3)πr^3
We have the value of r, which is 6.
Plug in the value, and solve.
V=(4/3)π(6^3)
V=(4/3)π(216)
V=π(288)
V=904.7786842
So, C. is your answer.
