a stadium floor that is in the shape of a circle has a diameter with length of 210 yards. which of these measurements is closest

Len [333]

<span>The stadium floor has a diameter of 210 yards, therefore the radius would be 105 yards

The Area of a circle is Pi times radius^2

A = Pi x 105yd^2
A = Pi x 11025yd
A = </span>34636.06 yd<span>
