Help! If a sphere has a radius of 8mm, what is its volume? (Show work)

babymother [125]

The formula for the volume of a sphere is V = (4/3) * π * r³. Knowing this, we can plug in the radius:

$V = \frac{4}{3} \pi *8^{3} \\ V = \frac{4}{3} \pi*512 \\ V = 2144.66$

The sphere's volume is approximately 2144.66 mm^3.
