depends on the information given, but radius is half of the diameter.
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
Not enough information is given to work out the radius of the circle as for instance what is the length of sector's arc in degrees
Work it out the circumfrance of a circle is pie x the diameter!
the radius of a circle is r
The radius of a circle is half the circle's diameter
By dividing the diameter by 2 will give the circle's radius. Area of any circle = pi*radius squared.
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.

The circumference of a circle with a known radius and can calculated using the following formula: C = 2Π(r)
Pi times the square of the radius.
Work it out the circumfrance of a circle is pie x the diameter!
c=2*pie*r c= circumference r= radius.
the radius of a circle is r
The radius of a circle is half the circle's diameter
U work it out
Work out the length of the coordinates and half it.
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
