The area of a circle with radius r is calculated using the formula below.
A=Ď€ r^2
From the figure, we know that the radius of the circle is 8.5m. By substituting 8.5 for r in the formula, we can calculate A. We will use π=3.14 for the calculations.
The area of the circle is approximately 226.865m^2.
