Multiply the diameter of a circle by Pi (3.1416) to calculate the circle's circumference.
In this case, 3' x 3.1416 = 9.4248 (foot circumference)
The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.
The circumference of a circle if its radius is 3 is about 18.85
Circumference of circle: 4*pi = 12.566 cm to 3 decimal places
A circle with a radius of 3 units has a circumference of 18.85 units.
For any circle in a plane, the ratio of circumference to diameter is a number called pi, approximately 3.14.
Multiply the diameter by Pi (about 3.1416). The result is the circumference:3 x 3.1416 = 9.4248 inches circumference
The circumference of a circle is 2*pi*r. With r = 3, the circumference is 6 pi.
The circumference of a circle with an area of 3 acres is: 1,281 feet.
The circumference of a circle with a radius of 3 m is: 18.85 m.
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
A circle with a radius of 3 units has a circumference of 18.85 units.
The circumference of a circle with a diameter of 3 meters is: 9.42 meters (diameter x Pi = circumference).
