Circumference to Radius of Circle Calculator
WebFeb 28, 2024 · Diameter of circle=18.6 cm. Formula for the radius of a circle = Diameter 2 = 18.6 2 = 9.3 cm. Solved Example 2: The circumference of a roller is 132cm. Determine the radius of the roller. Solution: Circumference of the roller=132 cm. Circumference of a circle= 2 π r. C = 132 = 2 × 22 7 × R. Therefore Radius (R)=21 cm. WebSo the circumference is equal to 2 pi r. Circumference 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 ... hierarchy ppt template free download
5 Ways to Calculate the Radius of a Circle - wikiHow
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. WebJan 26, 2024 · Circumference to diameter Find radius from circumference. The circumference equation using radius, C = 2πr, can also be used to find the radius of the circle if you know circumference.
