the radius is half of the diameter
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
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.
11.5 inches for a 23-inch diameter circle. If you meant the circumference is 23 inches, then the radius would be 3.6606 inches.
If you are talking about 9 and 12 inch diameter, then divide both by 2 to get the radius. The area of a circle is pi (3.1415 is good for most calculations) multiplied by the square of the radius. So for the 12 inch circle, the radius is 6. The square of the radius is 36, and multiplying this by pi gives approximately 113.1 square inches. Now the 9 inch circle has a radius of 9/2 or 4.5. Squaring this we get 20.25, which multiplied by pi is approximately 63.6 square inches. If 9 and 12 were already the radius in the problem, just don't divide by 2 since you already have the radius.
The diameter of a circle is the distance across the circle passing through its center. To find the diameter of a circle, you can simply double the length of the radius. If the circle has a radius of 24 inches, then the diameter would be 48 inches. So, the diameter of a 48-inch circle is also 48 inches.
A circle with a 12 inch diameter has a 6 inch radius.
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
The Diameter of a Circle is twice the Radius.thus for a 52 inch Diameter Circle the Radius will be 52/2=26 inches.
It is customary to call a circle a 38 inch circle if its diameter is 38 inches. If that is the case, the radius = diameter/2 = 19 inches.
12 inch diameter(also 6 inch radius).
d = 2r, where d is diameter and r is radius.
Radius of the circle: 3.65/2 = 1.825 inches
6 inch, because the radius the basically half of the diameter
The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 60 inches, the radius would be half of 60, which is 30 inches. The formula to find the radius from the diameter is: radius = diameter / 2.
32in
The diameter of a circle is twice the radius. Since the radius is half the diameter, if you have a circle with a diameter of 4.6 inches, it means the diameter is already 4.6 inches. Thus, the diameter of the circle is 4.6 inches.
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
