Answer:
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
