Question

The radius of a sphere is 6 units. Which expression represents the volume of the sphere, in cubic units?

Answer 1

By definition, the volume of a sphere is given by:

$V = (\frac{4}{3}) * (\pi) * (r ^ 3)$

Where,

r: sphere radio

Substituting values we have:

$V = (\frac{4}{3}) * (\pi) * (6 ^ 3)$

Note: all the expressions given, they need the factor 4/3

Answer:

An expression that represents the volume of the sphere, in cubic units is:

$V = (\frac{4}{3}) * (\pi) * (6 ^ 3)$
