Question

I need help to get the surface area. the circle throws me off. I will send a clear photo.

Answer 1

The surface area of a spehere is given by:

$A=4\pi r^2$

in this case we have a radius of 6.7 in. Then we have:

$\begin{gathered} A=4\pi(6.7)^2 \\ A=179.56\pi \\ A\approx564.10 \end{gathered}$

Therefore the surface area of the sphere is 564.10 squared inches.
