about 12.57 inches
Circumference of circle: 4 times pi 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
3.1416 x 4 inches = 12.566 inches
circumference = 4*pi inches
A circumference of 12.57 inches.
Diameter = 1.273 inches.
about 12.57 inches
If the diameter of a circle is 4 inches the circumference will be about 12.57 inches. (d x Pi = C)
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
Circumference of circle: 4 times pi 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
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
3.1416 x 4 inches = 12.566 inches
A circle with a radius of 4 inches has a circumference of 25.13 inches.
Ah, a circle is a beautiful thing, isn't it? If the circumference of a circle is 4 inches, we can find its diameter by using a simple formula. The diameter would be approximately 1.27 inches. Just imagine that circle on your canvas, bringing a sense of harmony and balance to your artwork.
It is 4/pi = 1.3 inches, approx.
