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
radius = square root of (78.5/pi) = 4.998732446 diameter = 2*4.998732446 = 9.997464892 or about 10 inches
20 mm. The diameter is always twice the radius.
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
Area = Pi multiplied by the radius squared Circumference = Pi multiplied by the diameter r = 10 in./2 = 5 in. A = (3.1415)(5 in.)(5 in.) = 78.54 in.2 C = (3.1415)(10 in.) = 31.42 in. Therefore, a small circle with a diameter of 10 inches has an area of about 78.54 inches squared and a circumference of about 31.42 inches.
The radius is half the diameter. The diameter is twice the radius. If the radius is 10 inches, the diameter is twice that, or 20 inches. The radius is any straight line that connects a point on the circle with it's center. The diameter is a line segment that connects two points on a cirle throught the center of the circle.Answer:Let r be the radius of the circle and d be the diameter of the circle. We know that the diameter = 2 * radius of the circle. Given the radius r = 10 inches. Diameter d = 2 * 10 Diameter = 20 inches.
If a circle has a diameter of 10 inches across it then its radius is half of 10 inches which is 5 inches.
If a circle has a diameter of 10 inches across it then its radius is half of 10 inches which is 5 inches.
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.
It is: 2*5 = 10 inches
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
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 radius of a circle is half of its diameter.
10 inches The diameter of a circle is twice the radius, so 1/2 of 20 inches is 10 inches. to make this sound easier: you just take half of the diameter. for instance lets say the diameter was 5. so your thinking: how can you split a odd number in half but you just turn the diameter of 5 and turn the radius into 2.5. u with me?? hoped i helped!! :) :)
The circumference of the circle if the radius marked r is 10 inches is: about 62.83 inches. You can easily do this calculation for other circles by multiplying the diameter (twice the radius) by Pi (about 3.1416).
The radius of a circle is half the length of its diameter. Therefore, if the diameter of the circle is 10 cm, the radius would be half of that, which is 5 cm. The formula to find the radius of a circle is r = d/2, where r is the radius and d is the diameter.
