Best ResponseYou've already chosen the best response.0so you need to find the radius so then the circumference formula is \[C = 2\pi r\] in your question you have \[27 = 2 \pi r\] make r the subject... when you have the value of r substitute it into the formula for surface area of a sphere \[SA = 4\pi r^2\]
