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.
