In a circle the length of an arc is given by
WebRounded to 3 significant figures the arc length is 6.28cm. The formula to calculate the arc length is: \[\text{Arc length} = \frac{\text{angle}}{360^\circ} \times \pi \times d \] WebSolution: 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) …
