Question

The circumference of a circle is 28 inches. What is the length of the radius of this circle?

Answer 1

Answer:

r = 4.4563384065731 in  

Step-by-step explanation:

If:

Circumference, C = 28 in

Then:

Radius, r = 4.4563384065731 in

Diameter, d = 8.9126768131461 in

Area, A = 62.388737692023 in2

r=C2π

d=Cπ

A=C24π

Answer 2

Answer:

4.46 inches(3sf)

Step-by-step explanation:

circumference= (pie)D so....

28/pie=8.912676813

8.12676813/2=4.456338407
