Answer:

97, 264.64 yd²

Explanation:

The circumference of a sphere is the circumference of the circle with the same radius:

C= 2πr

The area of a sphere is given by the formula...

A= 4πr²

In terms of circumference, that is...

A= 4π(C/(2π))²=C²/π

Using the given values, the area of the sphere is ...

A= (552.64 yd)²/3.14= 97, 264.64 yd²
