so 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 \[SA = 4\pi r^2\]

4pir^2 4*3.14(27/2)^2 12.56(13.5)^2 12.56*182.25 2,289.06

I think your value for the radius is incorrect @heathernelly
