Question

If the arcs of the same length of two circles subtend 75° and 140° at the centre then the ratio of the radii of the circles is ?

Answer 1

I have tried to answer hope it helps you

Answer 2

Answer:We know that length of an arc is given by,

S = R*X , where X = angle subtended by the arc at center in degrees.

Using this,

S = A*60

S = B*75 ,

ratio of radii = A/B = 75/60 = 5/4
