Remember that the area of a circle with radius r is calculated using the formula below.
A=Ï€ r^2
Here, r is the radius of the circle. To find the area, we need to start by finding the value of the radius of the circle. Since the circumference is 50.24m, we can use the formula for the circumference to find the radius of the circle.
C=2Ï€ r
We will substitute 50.24 for C in the formula and solve the resulting equation for r. We will use 3.14 for π.
