Generally, when finding the circumference of a circle, then formula is c=2*3.14*r (where r is the radius)
Substitute the given values
408.2= 2*3.14*r
R is 65
Now that we know that the radius is 65, the formula for the area of a circle is a=3.14*r^2
Substitute the given values
3.14*65^2
Therefore, the area of the circle is 13266.5 metres squared
