If the diameter of a circle is 4 inches the circumference will be about 12.57 inches. (d x Pi = C)
Diameter = 1.273 inches.
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
A circle with a radius of 4 inches has a circumference of 25.13 inches.
about 12.57 inches
Circumference of the circle: 4 times pi in inches
Circumference of circle: 4 times pi in inches
It is 4/pi = 1.3 inches, approx.
circumference = 4*pi inches
yes
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square 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
