circumference = 2 x π x radius
→ radius = circumference/(2 x π)
area = π x radius2
= π x (circumference/(2 x π))2
= circumference2 / (4 x π)
= (10 cm)2 / (4 x π)
= 25/π cm2
If a circle's diameter is 10, the circumference is: 31.416
Using 3.14 as Pi the area of circle is: 0
The circumference of a 10-inch diameter circle is: 31.42 inches.
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.
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
The circumference is 62.8318531 inches.
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
This circle's area would be 78.54 units squared.
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.
If a circle's diameter is 10, the circumference is: 31.416
Area = 78.54 cm2Circumference = 31.42 cm
Using 3.14 as Pi the area of circle is: 0
Divide the circumference of 62.8 by 2*pi to find the radius which is about 10 units Area of the circle: pi*10*10 = 100*pi square units
Circumference of circle: 10*pi feet
