The circumference is 9.42 dm. Find the area of the circle bounded by this circle.

To find the area of a circle, we need the formula:

S = п * R ^ 2,

Since R is still unknown to us, we will find it using the following formula:

L = 2 * п * R

In order to find the radius, we transform this formula:

R = L / 2 * п, respectively:

R = 9.42 / 2 * 3.14 = 9.42 / 6.28 = 1.5dm

Now we are looking for the area of the circle:

S = 3.14 * 1.5 ^ 2 = 7.065 dm ^ 2

Round to hundredths 7.065 dm = 7.07 dm ^ 2

Answer: The area of a circle is 7.07 dm ^ 2
