The diameter of a circular rug is 5.6 feet what is the radius and circumference and area

radius = 2.8 ft

circumference = 17.584 ft

area = 24.62 ft²

Step-by-step explanation:

Diameter of a circle is also two times the radius, or d = 2r, where d = diameter and r = radius.  If diameter is 5.6, radius is:

5.6 = 2r (divide by 2) r = 2.8 ft.

The formula for the circumference of a circle is:  C = 2πr or C = dπ, where r = radius, d = diameter and π = 3.14.  For the rug:

C = 5.6π or 5.6(3.14) = 17.584 ft.

The formula for area of a circle is:  A = πr². For the rug:

A = 3.14(2.8)² = 24.62 ft²
