The radius is 2.25 dm. Find the area and length of the circle.

Let’s solve this problem by consistently answering the questions:

1). Find the area of the circle:

S = пR ^ 2 = 3.14 * (2.25) ^ 2 = 3.14 * 5.06 = 15.8884 dm ^ 2.

2). Find the length of the circle:

P = 2пR = 2 * 3.14 * 2.25 = 14.13 dm.

Answer: S = 15.8884 dm ^ 2, P = 14.13 dm.
