Multiply the radius by (2 x pi).
The circumference of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a diameter of 1 inch, the radius is 0.5 inches. Therefore, the circumference is ( C = 2\pi(0.5) = \pi ) inches, which is approximately 3.14 inches.
A circle with a radius of 1 meter has a circumference of 6.28 meters.
circumference = 2 * pi * r ----> pi is a constant in this case circumference = 2 * 3.142 * 10 ------> radius is 1/2 of a diameter So, circumference of this circle is 62.84 inches
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
Circumference of the circle is: 2 times pi
circumference of a circle = diameter*pi or 2*pi*radius
The circumference of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a diameter of 1 inch, the radius is 0.5 inches. Therefore, the circumference is ( C = 2\pi(0.5) = \pi ) inches, which is approximately 3.14 inches.
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
A circle with a radius of 1 meter has a circumference of 6.28 meters.
circumference = 2 * pi * r ----> pi is a constant in this case circumference = 2 * 3.142 * 10 ------> radius is 1/2 of a diameter So, circumference of this circle is 62.84 inches
area of a circle = pi * radius² = 1 radius = √(1/pi) circumference = 2pi * radius = 2pi * √(1/pi) = 3.5449077
Circumference of the circle is: 2 times pi
0.5
6.28
If the radius is 1, the diameter is 2, and the circumference is about 6.28. Since the area of a circle is πr^2, a circle with r=1 would have an area of π.
The circumference of an 8-inch circle is: 25.1 inches.
Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).
