Question

find the volume of the sphere. round your answer to the nearest tenth. 28 m 8 the volume is about cubic meters.

Explanation:

Step1: Find the radius

The diameter \(d = 28\) m. The radius \(r=\frac{d}{2}\), so \(r=\frac{28}{2}=14\) m.

Step2: Use the volume formula for a sphere

The volume formula of a sphere is \(V=\frac{4}{3}\pi r^{3}\). Substitute \(r = 14\) into the formula:

$$

$$

Step3: Calculate the numerical value

Take \(\pi\approx3.14\), then \(V=\frac{10976}{3}\times3.14\approx\frac{10976\times3.14}{3}\approx\frac{34464.64}{3}\approx11488.2\)

Answer:

\(11488.2\)
