Question

A volleyball has a surface area of about 227 square inches. Which of these could be the radius of the volleyball

Answer 1

18.1 inches

Explanation:

A volleyball is spherical in shape, and the surface area of a sphere is giving by the formula

`The surface area of sphere=4\pi r^(2)`

from the data giving, the surface area was calculated to be 227 square inches. from the above formula, we define the radius, r to be the subject of formula, we arrive at

`\sqrt{(SA)/(4\pi )} =r`

if we substitute for the surface area, we arrive at

`r=\sqrt{(227)/(4\pi ) } \\r=18.1inches`

Hence the radius of the volleyball will be 18.1 inches
