Hello!

We must use a certain formula to find the circumference of anything circular.

The formula is:

C = 2 × pi × r

We know that pi = 3.14 approximately and the radius is 3 feet.

Substitute:

C = 2 × 3.14 × 3

C = 6.28 × 3

C = 18.84 ft

ANSWER:

The circumference of the circular rug is 18.84 ft. (Last option)

The circumference of a circular rug with a radius of 3 feet is equal to 18.84 feet.

Given the following data:

  • Radius of circular rug = 3 feet.
  • π = 3.14.

How to calculate the circumference of a circle?

Mathematically, the circumference of a circle is calculated by using this formula:

Circumference = 2πr

Where:

r is the radius of a circle.

Substituting the given parameters into the formula, we have;

Circumference = 2 × 3.14 × 3

Circumference = 18.84 feet.
