Question

in the formula $\frac{4}{3}pi r^{3}$, what does $r$ represent?
a. height
b. volume
c. diameter
d. radius

Explanation:

The formula $\frac{4}{3}\pi r^{3}$ is the formula for the volume of a sphere. In the formula for the volume of a sphere \(V=\frac{4}{3}\pi r^{3}\), \(r\) represents the radius of the sphere. The height is not relevant in the standard sphere volume formula. Volume is \(V\) (the result of the formula). The diameter \(d = 2r\), but \(r\) itself is the radius. So \(r\) represents the radius.

Answer:

D. Radius
