Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
Divide the known circumference by pi to find the diameter of the circle.
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given that the circumference is 6 inches, you can plug this value into the formula: 6 = π * diameter. To solve for the diameter, you divide both sides by π, resulting in diameter = 6 / π ≈ 1.91 inches.
To find the diameter of a circle with a circumference of 66 inches, you can use the formula C = πd, where C is the circumference and d is the diameter. Rearranging the formula to solve for d, you get d = C / π. Plugging in the circumference of 66 inches, the diameter would be 66 / π ≈ 21 inches.
To Find Diameter:Multiply circumference by 0.3183, ordivide circumference by 3.1416Other things to do with circles:To find Circumference:Multiply diameter by 3.1416, ordivide diameter by 0.3183To Find Radius:Divide diameter by 2, ormultiply circumference by 0.15915, ordivide circumference by 6.28318
a circle with circumference of 25.56 inches.
Multiply the diameter by pi to find the circle's circumference
The circumference of a circle with a diameter of 18 inches is 56.5 inches.
In order to find the diameter of a circle, you have to take the circumference of the circle and divide by Pi for which you can use the approximation: 3.14. So if the circumference of the circle is 60 inches, you divide that by Pi (3.14) and get a diameter of 19.0985 inches.
The circumference and area of a circle with diameter of 12 inches are:C = 37.7 inchesA = 113.1 square inches
To find the diameter of a circle with a circumference of 60 inches, you can use the formula: circumference = π * diameter. Given that the circumference is 60 inches, you can plug this value into the formula: 60 = π * diameter. Solving for the diameter, you get diameter ≈ 19.1 inches.
Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
Multiply the diameter by Pi:8 inches x Pi (about 3.1416) = 25.1328 inches circumference
circumference = 4*pi inches
Divide the circumference by Pi.
Remember the circle eq'n C = pi d Algebraically rearrange d = C / pi Hence C = 19/3.141952.... C = 6.047887837... inches.
The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.
