19 lip 2024 · Problem 4: A circle has an arc of length 10π/3 cm and this arc subtends a central angle of 120 o degree. Calculate the radius of the circle. Solution: By the arc length formula, Arc length = 2πr (θ/360) 10π/3 = 2πr(120 / 360) Divide by π on both sides, 10/3 = 2r(1/3) or, 2r/3 = 10/3. r = 5cm. Therefore, the radius of circle is 5cm.
