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
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
radius *2 = diameter so then plug the radius in... 4*2=8 8 is the diameter of the figure.
The diameter is double the radius, and the radius is 1/2 of the diameter.If the radius is 8 cm, then the diameter is 16 cm.
Radius = 1/2 diameter. So, if the diameter is 8", then radius of the circle is 4".
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
Diameter is 16. The radius is half its diameter
Diameter = double the radius = 16
Diameter = 2*Radius
8 inches. Radius is ½ diameter.
Diameter = 2 times radius = 8
If the radius is 8 feet then the diameter will be 16 feet.
