We need to find the area of the given circle. Similar to the perimeter, the area of a circle with radius r is calculated using the formula below.
A=Ï€ r^2Let's now draw the diagram of the circle.
In the diagram we can see that the diameter is 13.1 centimeters. Therefore, the radius is 13.1÷ 2= 6.55 centimeters. We can substitute this value for r in the formula for the area of a circle and simplify.
