R(10)The radius is 1.59 feet (c=2 x PI x r)
The circumference of a 10-inch diameter circle is: 31.4 inches.
The circumference is 62.8318531 inches.
10 * pi = 31.4159...
10.0
Circumference of circle: 10*pi feet
The circumference of a circle if the diameter is 10 feet long is: Pi x 10 (about 31.416).
If the circumference of a circle is 10 feet the radius is: about 1.592 feet. For this type of calculation, divide the circumference by Pi (about 3.1416). This gives you the diameter. Next, divide the diameter by two to get the radius.
The circumference of a circle with a diameter of 10 ft is: 31.42 feet (diameter x Pi = circumference).
There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.If the circumference is 10 feet, that would make the diameter 3.183 feet.
Diameter = 10/pi = 3.183098862 feet
The circumference is easy to calculate: diameter x Pi (about 3.1416) = circumference. So,10 feet x 3.1416 = 31.416 feet circumference.
The formula for circumference is 2 x pi x radius. For a circle of 10 feet, the cirumference would be 62.8 feet. The formula for area is pi x r2. For a circle of 10 feet, the radius would be 314.16 ft.
10 ft???? =XD
Circumference = 2*Ï€*radius = 20*Ï€ feet
It is: 2*pi*10 = 62.832 feet rounded to three decimal places
The circumference is pi times the diameter of the circle. Diameter is twice the radius, so the diameter is 10 feet. With pi approximately 3.14, the circumference (linear feet perimeter) is 31.4 feet.
