Web2. We can pretend to measure the circumference of a circle by saying circumference = π * diameter. Since π itself is an approximation, a "measurement" of the circumference will always and forever be just an approximation and NEVER an exact number. It is quite interesting because one can clearly see a circle has bounds unlike a straight line ... WebThe diameter of circle C is 20 centimeters. Which measurement is closest to the difference between the circumference of circle B and the circumference of circle C in centimeters? …
WebCircumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference was 12pi. Up next: video
