The Radiusis the distance from the center outwards. The Diametergoes straight across the circle, through the center. The Circumferenceis the distance once around the circle. And here is the really cool thing: We can say: Circumference = π× Diameter Also note that the Diameter is twice the Radius: … See more Put a pin in a board, put a loop of string around it, and insert a pencil into the loop. Keep the string stretched and draw the circle! See more Try dragging the point to see how the radius and circumference change. (See if you can keep a constant radius!) See more The area of a circle is πtimes the radius squared, which is written: A = π r2 Where 1. Ais the Area 2. ris the radius Or, using the Diameter: A = (π/4) × D2 See more The length of the words may help you remember: 1. Radiusis the shortest word and shortest measure 2.

WebThere’s a nice way to see why the formula for the area of a circle of radius R is: Pi * R 2. It has an interesting relationship with the formula for the circumference of a circle, which is 2 * Pi * R (and that is a consequence of the definition of Pi, which is defined to be the ratio of the circumference of a circle to its diameter.) So ... WebThe formula for finding the circumference includes the diameter, and looks like this: C = \pi π d. To make this easier, we can also find the circumference if we know the radius of a circle. We know that the diameter is equalled to 2r (2 times the radius), so in other words, the formula for a circle's circumference is: C = 2 \pi π r. WebCircle Worksheets.
