Answer:
A = 539.8 yd²
Step-by-step explanation:
1) Determine the radius of the sphere. Recall that C = 2πr, so that r = C/[2π]. Here, C = 540.08 yd, and thus r = (540.08 yd) / [2π] = 85.956 yd.
The surface area of this sphere is given by A = 4π*r², which here equals:
A = 4π*r² = 4(3.14)(85.956 yd)²
or
A = 539.8 yd²
