Question

What is the volume of a sphere with a diameter of 7.6 cm, rounded to the nearesttenth of a cubic centimeter?

Answer 1

Given:

Diameter = 7.6 cm

To find the volume of the sphere, use the formula below:

$V\text{ = }\frac{4}{3}\pi r^3$

Where,

π = 3.142

r = diameter/2

$r\text{ = }\frac{d}{2}=\text{ }\frac{7.6}{2}\text{ = }3.8\text{ cm}$

Volume of the sphere:

$\begin{gathered} V\text{ = }\frac{4}{3}\pi r^3 \\ \\ \text{ = }\frac{4}{3}\ast3.142\ast3.8^3 \\ \\ \text{ = }229.9cm^3 \end{gathered}$

ANSWER:

$V=229.9cm^3$
