diameter is 2 times the radius 24

The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

Well to find the radius it is diameter/2.

same as for a whole circle

The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.

You already know the radius.

The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).

It is twice the radius of a circle

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.

It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.

Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi

The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
