The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
Circumference is simply pi times the diameter. The approximate value of pi is 3.14, so for a circle 4 feet in diameter, the circumference is 4 x 3.14 = 12.56 feet, approximately.
A circle with a radius of 4 inches has a circumference of 25.13 inches.
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The circumference of 1.5 diameter is: 4.712
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
To find the diameter divide the circumference of the circle by pi
12.5663706144, because the diameter (4) times Pi equals circumference
If a circle has a diameter of 4 bananas, it's circumference is 12.564 bananas
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
The circumference of the circle that has a diameter of 4 feet is: 12.57 feet
The circumference = Pai x Diameter = 3.14 x 4 = 12.56 cm
Circumference of circle: 4 times pi in inches
