So we want to find the radius of the circle. So just divide 56.52 by 3.14 and 2, which is 9. And then to find the area, just square 9 and multiply it by pi, which is 354.34 square inches.

The area of the rug is 354.34 square inches.

l/D=π⇒D=l/π=56,52/3,14=18(inch)
S=πD²/4=3,14*18²/4=254,34(inch²)
