What is the area of a circle with a radius of 21cm?

The area of a circle is calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Plugging in the radius of 21cm into the formula, we get A = 3.14159 x (21)^2 = 1385.44 square centimeters. Therefore, the area of a circle with a radius of 21cm is 1385.44 square centimeters.
