To find the area of the rug, we first need to find the radius of the circle.
The formula for circumference of a circle is: C = 2πr
Given that the circumference is 62.8 inches:
62.8 = 2πr
r = 62.8 / (2π)
r = 62.8 / (2 * 3.14)
r = 9.99 inches
Now that we have the radius, we can find the area using the formula for the area of a circle:
A = πr^2
A = 3.14 * (9.99)^2
A = 3.14 * 99.80
A = 313.632 square inches
Therefore, the area of the rug is 313.632 square inches.
Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 62.8 inches.
