Question

find the volume of this sphere. use 3.14 for π. 9 cm volume of a sphere v = \frac{4}{3}πr^{3}

Explanation:

Step1: Find the radius

The diameter is \(9\) cm, so the radius \(r=\frac{9}{2} = 4.5\) cm.

Step2: Substitute into the volume formula

The volume formula of a sphere is \(V=\frac{4}{3}\pi r^{3}\). Substitute \(r = 4.5\) and \(\pi=3.14\) into the formula:
