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

$r=\sqrt{\frac{S}{4pi}}$

where

S=6161 in2

pi=3.14

substitute

$\begin{gathered} r=\sqrt{\frac{616}{4*3.14}} \\ \\ r=7.0\text{ in} \end{gathered}$

The answer is the option C
