For any grade, the formula for circumference is as follows: C = Pi x D Where C=Cirucmference, Pi = 3.14159, and D = Diameter
Using the formula for circumference, the diameter can be found. The formula is C = Pi x D where Pi = 3.1416 and D = Diameter. C = Pi x D (sub with known numbers) 25.12 = 3.1416 x D (divide both sides by Pi) 25.12 ÷ 3.1416 = D 7.9959 = D
To find the diameter of a circle given its circumference, you can use the formula ( C = \pi d ), where ( C ) is the circumference and ( d ) is the diameter. Rearranging the formula gives ( d = \frac{C}{\pi} ). For a circumference of 88, the diameter would be ( d = \frac{88}{\pi} \approx 28.0 ) units.
