Formula for finding radius from circumference
WebNov 28, 2024 · What is the radius of a circle with a circumference of 34.54 feet? Solution. To work on this problem, you will need the formula for finding the circumference of a circle using the diameter. \(C=\pi d\) First, fill in the given information. \(34.54=(3.14)d\) Next, solve the problem by dividing both sides by 3.14. 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) + 12.56 = 32.56 feet. Find the arc length of a sector …
