WebThe length of an arc of a circle is given r*theta (in radians). Here we have two circles with centers O1 and O2. Arc of circle O1, of radius r1 = r1* (60/180) and arc of circle O2, of radius r2 = r2* (75/180). Since the lengths of the arcs is the same r1* (60/180) = r2* (75/180), hence r1/r2 = 75/60 or 5/4. Web26 jul. 2024 · Best answer Angle in radians = Angle in degrees × π 180 π 180 θ = 1/r Where θ is central angle, L = length of arc, r = radius Therefore θ1 = 75 x π 180 π 180 = 5π 12 …
