find the area of the circle if the radius is 11cm
To find the area of a circle, we use the formula: A = πr^2 where r is the radius of the circle.
Given that the radius is 11cm, we can plug this value into the formula:
A = π(11)^2
A = π(121)
A = 121π
Therefore, the area of the circle with a radius of 11cm is 121π square centimeters, or approximately 381.70 square centimeters.
