Radius of circle using area
WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large. WebDec 3, 2015 · Radius or Diameter of a Circle Given Area To find the radius, divide the area by pi, then take the square root.
