v = 36 pi r^3v=36πr3 or v = 113.097 r^3v=113.097r3

Explanation:

The volume of a sphere is computed using this formula

v = 4/3 pi r^3v=43πr3

such that:
vv = volume
rr = radius of the sphere

In this case, since you have a sphere with radius = 3rradius=3r then you would need to substitute the given radius of the sphere to the value of rr in the formula.

v = 4/3 pi r^3v=43πr3
v = 4/3 pi (3r)^3v=43π(3r)3
v = 4/3 pi (27r^3)v=43π(27r3)
v = 36 pi r^3v=36πr3
v = 113.097 r^3v=113.097r3
