Find the length of the radius of the circle
WebCalculate the radius of a circle whose arc length is 144 yards and arc angle is 3.665 radians. Solution. Arc length = r θ. 144 = 3.665r. Divide both sides by 3.665. 144/3.665 = r. r = 39.29 yards.

WebCircle X Possible Answers: 4 √12 7 6 Correct answer: 6 Explanation: Find the total area of the circle, then use the area formula to find the radius. Area of section A = section B = section C Area of circle X = A + B + C = 12π+ 12π + 12π = 36π Area of circle = where r is the radius of the circle 36π = πr2 36 = r2 √36 = r 6 = r Web1. Let the center be O. It says the chord of length 10 is bisected at (4,-3). Let the chord be AB and its mid point be D which is (4,-3). Now we know, the perpendicular from center to a chord bisects it, so we have two right angular triangles, ∆OAD and ∆OBD where OA will be radius, r. You can calculate OD by using the distance formula.
