Question

the diameter, d, of a sphere is 12.4 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.)
v = □ m³

Explanation:

Step1: Find the radius

The radius \( r=\frac{D}{2} \). Given \( D = 12.4\ m \), so \( r=\frac{12.4}{2}=6.2\ m \).

Step2: Use the volume formula for a sphere

The volume formula of a sphere is \( V=\frac{4}{3}\pi r^{3} \). Substitute \( \pi = 3.14 \) and \( r = 6.2 \) into the formula:
