The circumference of the circle that has a diameter of 4 feet is: 12.57 feet
The circumference of a circle if the radius is 4 is about 25.13 units. (C = r x 2 x Pi)
When the diameter of the circle doubled, its circumference also doubled.However, its area increased to 4 times the original area, while nobody was looking.
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
the diagonal of the rectangle will be the diameter of the circle which equals 5 so the circumference will be 5pie or 15.70units.
If the diameter of a circle is 4 inches the circumference will be about 12.57 inches. (d x Pi = C)
A circumference of 12.57 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
