Circumference = 2*pi*radius or pi*diiameter
Circumference = 31.416 units rounded to 3 decimal places
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
Circumference of any circle = (pi) x (diameter) Diameter = 2 x radius
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.
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95

circumference of a circle = 2*pi*radius or pi*diameter
Circumference of any circle = (pi) x (diameter) Diameter = 2 x radius
If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
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 diameter is 20. (The diameter is twice the radius. The radius is from the center to any edge of the circle.)The circumference is 62.83. ( The diameter X Pi (3.14... equals the circumference.)OR:Using only the radius: (2 X Pi X radius will also equal the circumference.)In this example 2 X 3.14 X 10 (2 X 3.14 = 6.28 X 10= 62.8)
you have to quote the diameter or radius or circumference of the circle to calculate the area. If diameter 78.53. If radius 314.15. If circumference 7.95

Impossible because the diameter of any circle is always twice its radius.
That depends on whether 10 miles is the diameter or circumference.
