If the radius is 8 what is the diameter?

Answer 1

If by an 8 inch circle, you mean that the circumference is 8 inches, then

the radius would be found using:

C =pi x diameter

8 =3.14 x diameter

8/3.14= diameter

and since diameter = 2 x radius

2.55 = 2 x radius

2.55/2 = radius

therefore, the radius is approximately 1.27 inches

Answer 2

The diameter is the radius squared, so the diameter is 16. 16 radius is 1/2 across and diameter is across. Acording to its roots dia means across and meter means measure.

Answer 3

4 inches. The radius is half of the diameter

Answer 4

4"

Answer 5

200.96 ft
