Find the area of the circle if the length is 37.68 cm.

Let us determine the area of the circle, if the length is known 37, 68 cm.

To determine the area you need to find its radius.

And so l = 2 п R, where п is a constant 3, 14; R is the radius.

Let us express R = l / 2 п.

Substitute R = 37, 68/2 * 3, 14.

R = 37, 68/6, 28.

R = 6 cm.

Now you can find the area.

S = п * R 2

S = 3.14 * 6 2 = 113.04 cm2

Answer: the area of the circle is 113, 04 cm 2
