What is the Formula for the Area of a Circle?

What is the formula for the area of a circle?

Summary

  1. We can create a parallelogram by laying the circumference out in two lines
  2. Then we can fit the wedges of the circle into the parallelogram
  3. C stands for the circles circumference
  4. r stands for the radius of the circle
  5. The area of the parallelogram should be very close to the area of the circle

Notes

    1. We can take our sliced up circle and turn it into a parallelogram by laying parts of it out flat
    1. The area of the parallelogram should be very close to the area of the circle
    1. Let's find the area of our circle
