Question

the diameter, d, of a sphere is 7.6 mm. 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 \(r\) of a sphere is half of the diameter. Given \(D = 7.6\) mm, so \(r=\frac{D}{2}=\frac{7.6}{2}=3.8\) mm.

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 \(r = 3.8\) into the formula:
