Oh, what a happy little question! To find the area of a circle, we use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius. So, for a circle with a radius of 20 cm, the area would be A = 3.14 x 20 x 20 = 1256 square centimeters. Just imagine all the beautiful colors you could paint in that space!
