Question

the diameter, d, of a sphere is 11.2 m. calculate the spheres volume, v.
use the value 3.14 for π, and round your answer to the nearest tenth. (do not round any intermediate computations)

Explanation:

Step1: Find the radius

The radius \( r=\frac{D}{2} \). Given \( D = 11.2\) m, so \( r=\frac{11.2}{2}=5.6\) m.

Step2: Use the volume formula for a sphere

The volume formula of a sphere is \( V=\frac{4}{3}\pi r^{3}\). Substitute \( r = 5.6\) m and \( \pi=3.14\) into the formula:

Step3: Round to the nearest tenth

Rounding \(731.3565867\) to the nearest tenth gives \(731.4\).

Answer:

\(731.4\)
