Question

Find the volume of the sphere radius is 20 meters

Answer 1

4000/3(pi) or
4188.79 [corr to 2 decimal place]

the formula to the volume of sphere is [V= 4/3(pi)(radius)^3]. if the diameter of the sphere (which is as shown as in the picture provided) is 20 meters, the radius is 10 meters.

Answer 2

Using the formula 4/3*pi*r^3=V
V= 1675.52

Hope works for u :)
