Question

What expression gives the volume of a sphere with radius 8

Answer 1

V=(4/3)(pi)(r^3)
V=(4/3)(pi)(8^3)
V=(4/3)(pi)(512)
V=(2048/3)(pi), or around 2144.660585

Answer 2

Answer:

The volume of the sphere is 2144.66 cubic units

Explanation:

The volume of the sphere is given by = $\frac{4}{3}\pi r^{3}$

Now, we have been given the radius as 8 units. So, putting r=8 in the formula we get,

V= $\frac{4}{3}*3.14*8^{3}$

= $\frac{4*3.1415*512}{3}$

= 2144.66 cubic units.

So, the volume of the sphere is 2144.66 cubic units.
