Answer:
18.1 inches
Step-by-step explanation:
A volleyball is spherical in shape, and the surface area of a sphere is giving by the formula
[tex]The surface area of sphere=4\pi r^{2}[/tex]
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
[tex]\sqrt{\frac{SA}{4\pi }} =r[/tex]
if we substitute for the surface area, we arrive at
[tex]r=\sqrt{\frac{227}{4\pi } } \\r=18.1inches[/tex]
Hence the radius of the volleyball will be 18.1 inches
