Answer:
option C
Step-by-step explanation:
The sphere can be thought of as two hemispheres joined together. The formula for the volume of a sphere is:
V = (4/3)πr^3
where r is the radius of the sphere.
Since we are given that the radius of the sphere is 5 units, we can substitute this value into the formula:
V = (4/3)π(5^3) = (4/3)π(125) = 166.67 cubic units
Therefore, the approximate volume of the sphere is 166.67 cubic units, which is option C.
