The radius will be half the diameter of 8 inches which is 4 inches
Radius = 1/2 (diameter) = 25 inches.
If the diameter of the circle is 37 in, the radius is 18.5 in
1256 inches ++ Another Answer ++ The formula for finding the Circumference of a circle is C = Pi x D where D is Diameter and Pi is 3.1416. The Radius of a circle is one-half of the Diameter, hence the Diameter of a circle with a 20-inch Radius is 40 inches. Using the formula above, multiply 40 x 3.1416 to find the Circumference: 40 x 3.1416 = 125.664 inches.
Radius = Diameter/2. So in this case 4.5 inches.
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 diameter of a circle is twice the radius.
The radius of a circle is one-half of the circle's diameter. So if the radius is 12 inches, the diameter is 24 inches.
8 inches; the diameter of a circle is twice its radius.
The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
A circle 14 inches in diameter has a radius of 7 inches, and a circle having a radius of 7 inches has a diameter of 14 inches.
The diameter is essentially twice the radius, so therefore a circle with a radius of 54 inches has a diameter of 108 inches.
Two inches. The radius of a circle is 1/2 of the diameter.
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.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
6 inches. always multiply radius by 2 to get diameter
its 4..... the radius of a circle is half of the diameter
