Higgins bought a circular area rug that has a diameter of 72 inches. Which is closest to the area of the rug? Use 3.14 for p.
113.04 in.2
226.08 in.2
452.16 in.2
4,069.44 in.2
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 72 inches, the radius would be half of that, which is 36 inches.
Plugging in the values:
A = 3.14 * 36^2
A = 3.14 * 1296
A = 4064.64
So, the closest area of the rug would be approximately 4064.64 in^2, which is closest to 4,069.44 in^2.
