Question

Find the radius of the ball if it has surface area of 60 pi square inches

Answer 1

Step-by-step explanation

We will use the surface area formula for a sphere to find the radius:

`\begin{gathered} S=4\pi *r^2 \\ \end{gathered}`
`\begin{gathered} 60\pi=4\pi *r^2 \\ (60\pi)/(4\pi)=r^2 \\ 15=r^2 \\ √(15)=r \end{gathered}`

Answer

`√(15)\text{ In}`
