Question

The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi

Answer 1

49.6 square meters

Explanation:

first, circumference is 2*pi*r, so we want to find r. so we take 2*pi*r=24.8 and solve for r which is 4.

Now, area is pi*r^2 so pi*4^2 = pi*16 = 49.6

Answer 2

49.6 square meters.



First, let’s find the radius of the rug. The radius is equal to the circumference divided by 2pi, or 2 * 3.1, which is 6.2, in this case.

24.8/6.2

4

The radius is 4. The area of a circle is pi times the radius squared.

3.1 * 4^2

3.1 * 16

49.6

So, the area of the rug is 49.6 square meters.
