calculate the area of a circle with a diameter of 22 m. leave your answer in terms of pi
The formula to calculate the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter of the circle is given as 22 m, we can find the radius by dividing the diameter by 2:
r = 22 m / 2 = 11 m
Now, we can substitute the radius into the formula:
A = π(11 m)^2
A = π(121 m^2)
A = 121π m^2
Therefore, the area of the circle with a diameter of 22 m is 121π square meters.
