Best ResponseYou've already chosen the best response.0For the second question, circumference is given by\[C = 2 \times \pi \times r\]Rearranging, you can determine the radius using\[r = \frac{ C }{ 2\pi } \]With the radius known, the surface area of a sphere is calculated using\[SA _{\text{sphere}} = 4\pi r^2\]
