## How do you measure a round area rug?

If you’re considering a round rug, run a piece of tape from the center of the space you want to cover to the outside edge and measure it. This gives you the radius of the circle. Double it and you have the diameter. Round rugs are sold by the diameter.

## What is the formula for the area around a circle?

A = π r²

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

**How do you find the radius of the rug?**

Find: Radius (R) of Rug rounded to the nearest tenth of a foot. R is the positive square root. R ≈ √49.975 => R ≈ 7.07 Rounded = 7.1 ft. The area of a circle is the square of the radius multiplied by pi (3.1416).

### How do you calculate the area of a round room?

The area of circle is calculated by using the following listed formulas:

- Area = π × r2, where ‘r’ is the radius.
- Area = (π/4) × d2, where ‘d’ is the diameter.
- Area = C2/4π, where ‘C’ is the circumference.

### How do you figure the diameter of a circle?

To calculate the diameter of a circle, multiply the radius by 2. If you don’t have the radius, divide the circumference of the circle by π to get the diameter. If you don’t have the radius or the circumference, divide the area of the circle by π and then find that number’s square root to get the radius.

**What are the dimensions of a 6 foot round rug?**

Round rugs are measured by its diameter, the widest part of a circle. A 6′ round rug measures 6 feet (72 inches) in diameter.

#### How do you find the shaded area?

Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.

#### How does the diameter of the rug compared to its radius?

Dawn bought a circular rug. The radius of the rug was 1.5 feet. How does the diameter of the rug compare to the radius? The diameter of the rug is twice the radius.

**How many circles fit in a circle formula?**
