Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches

Multiply the radius by 2 to get the diameter. Then multiply the diameter by pi to get the circumference. Example: If radius = 2 inches, diameter = 4 inches circumference = 4 x pi = 4 (3.1416) or about 12.57 inches

A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.

Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches

Circumference = 2*pi*radius or circumference/2*pi = radius 90 inches/2*pi = 14 inches in radius =======================

Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches

diameter = circumference/pi = 37/3.1416 = 11.8 inches; radius = 1/2 diameter = 5.9 inches; radius = circumference/(2pi) = 5.9 inches = 37/6.2832 = 5.9 inches

If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches

Circumference = pi x diameter Hence Diameter = Circumference/pi Here Diameter = 26/3.1415 = 8.276 And Radius = Diameter/2, so Radius is 8.276/2 = 4.138 inches

A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.

Circumference = Pi multiplied by the diameter. C = (3.1415)(15 in.) = 47.12 in. Therefore, the circumference of a circle with a diameter of 15 in. and a radius of 7.5 in. is approximately 47.12 inches.

The inches in a diameter = 2 X inches in the radius. Or, inches in a diameter = inches in circumference / pi

What is 43 inches? The Area? The circumference? The Diameter? If the diameter is 43 inches than the radius is 21.5 inches If the Circumference is 43 inches than the radius is 6.96 inches If the Area is 43 inches than the radius is 3.7 inches Hope this is helpful :)
