WebThe area can be found by the formula A = πr2. Plugging our radius of 3 into the formula we get A = 9π meters squared or approximately 28.27433388 m2. Now we multiply that by (or its decimal equivalent 0.2) to find our … 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...

Arc Length - Formula, How to Find Length of an Arc

WebFind the area and perimeter of a sector with a radius of 10 feet and an arc length of 12.56 feet. Solution: The radius of sector = r = 10 feet Arc length = l = 12.56 feet Area of the sector without an angle = l r 2 = 12.56 × 10 2 = 62.8 sq. feet Perimeter of sector = 2 r + l = 2 ( 10) + 12.56 = 32.56 feet.
