Question

if the areas of same length in two circles subtend angles of angles of 60° and 75° at their centres​. Find the ratio of their radii​

Answer 1

Answer:

4:5

Step-by-step explanation:

let the length of two circles be and l1 and l2 respectively

now,

L1=L2 theta1=75 theta2=60

so,

R1 *theta1=R2.*theta2

R1/R2=theta2/theta1

=60/75=4/5=4:5
