The diameter is 106 yd. Remember that the radius is half the length of the diameter, so let's divide the diameter by 2.
r=106 Ă· 2 = 53
This means that the radius of the circle is 53 yd. Remember that the area of a circle with radius r is calculated using the formula below.
A=Ď€ r^2
We know that the radius of the circle is 53yd. By substituting 53 for r in the formula, we can calculate A. We will use 3.14 for π.
