Question

Two arcs of same length of two different circles
subtended angles of 25° and 75° at their centres
respectively. Then the ratio of the radii of the
circles is
(A) 3:1
(B) 1:3
(C) 1:2
(D) 2:1​

Answer 1

Answer:

step1- firstly write that angle 1 =25 and angle 2 = 75

step 2- then write as 75/25 and cancel it out you will get 3/1

step3 then write in ratio form 3:1 so answer is option A.
