Question

Use the given formula to find the radius of a sphere whose surface area S is 616 in2. Use 3.14 for π. Round your answer to the nearest tenth.r = square root s over 4 pie

Answer 1

we have the formula

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

where

S=6161 in2

pi=3.14

substitute

`\begin{gathered} r=\sqrt{(616)/(4*3.14)} \\ \\ r=7.0\text{ in} \end{gathered}`

The answer is the option C
