Question

what is the volume of a sphere with a radius of 7 cm? sphere $v = \frac{4}{3}\pi r^{3}$ 1. substitute the radius into the formula: $v = \frac{4}{3}\pi(7^{3})$ 2. evaluate the power: $v = \frac{4}{3}\pi(343)$ 3. simplify: $v = \square\pi cm^{3}$

Explanation:

Step1: Multiply the coefficient

Multiply \(4\) and \(343\): \(4\times343 = 1372\).
So the formula becomes \(V=\frac{1372}{3}\pi\).

Answer:

\(\frac{1372}{3}\)
