Explanation:
The formula is given below as
[tex]\begin{gathered} S=4\pi r^2 \\ where, \\ S=surfacearea=60ft^2 \\ r=radius \end{gathered}[/tex]
By substituting the values, we will have
[tex]\begin{gathered} S=4\pi r^{2} \\ 60=4\pi r^2 \\ r^2=\frac{60}{4\pi} \\ r^2=\frac{15}{\pi} \\ square\text{ root both sides } \\ r=\sqrt{\frac{15}{\pi}} \\ r=2.19 \end{gathered}[/tex]
Hence,
The final answer to the nearest hundredth is
[tex]2.19[/tex]
