Question

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!

Answer 1

Answer:

Volume, V = 3367.6 cm³

Step-by-step explanation:

Given the following data;

Diameter = 18.6 cm

Radius = diameter/2 = 18.6/2 = 9.3 cm

Pie, π = 3.14

To find the volume of the sphere;

Mathematically, the volume of a sphere is given by the formula;

$Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}$

Where;

r is the radius of the sphere.

Substituting into the formula, we have;

$V = \frac {4}{3} * 3.14 * 9.3^{3}$

$V = 4.186666667 * 804.357$

Volume, V = 3367.6 cm³
