WebIn order to derive the formula to calculate the angle at the centre of the sector, the formulae for the arc length and area of a sector can be rearranged so that we can calculate the fraction of ... WebExample 2: Calculate the length of the arc that subtends an angle of 40 degrees at the center of a circle with a radius of 6 cm. Solution: We know the arc length formula is y 360 2 π r. In this example, y = 40 and r = 6. Substituting these values in the example, we get. Arc length = 40 360 2 3.14 6 = 4.186 cm.
WebMultiplying both sides of the formula by d d gives us C = \redD\pi d C = πd which lets us find the circumference C C of any circle as long as we know the diameter d d. Using the formula C = \pi d C = π d Let's find the circumference of the following circle: 10 10 The diameter is 10 10, so we can plug d = 10 d = 10 into the formula C = \pi d C = πd:
