Question

Elijah bought a circular rug for his bedroom. The rug has a circumference of 22 feet. What is the radius of the rug, to the nearest tenth of a foot?

Answer 1

The radius of the rug is approximately 3.55 feet (to the nearest tenth).

Step-by-step explanation:

The circumference of a circle is given by the formula:

C = 2πr

where C is the circumference and r is the radius. We are given that the circumference of the rug is 22 feet, so we can use this information to find the radius:

22 = 2πr

Dividing both sides of the equation by 2π gives:

r = 22 / (2π)

Using a calculator to approximate π to the nearest tenth (3.1), we have:

r ≈ 22 / (2 * 3.1)

r ≈ 3.55

Therefore, the radius of the rug is approximately 3.55 feet (to the nearest tenth)
