Answer:
Replace the radius into the equation and compute the area
Step-by-step explanation:
The area of a circle is computed as follows:
area of a circle = π*r²
where <em>r</em> is the radius of the circle.
I cannot understand which radius has the circle. In the case that r = 3 yards, the area is:
area of a circle = π*(3)² = 28.3 yd²
And in the case that r = 5 yards, the area is:
area of a circle = π*5² = 78.5 yd²
