Question

theratio between two area of two circles is 16:9 . find the ratio between their diameter​

Answer 1

area of circle is πr square

ratio of area is 16:9

let radius of first circle and second circle be r1 and r2. respectively

πr1square :πr2square =16 :9

r1square:r2 square =16:9

r1:r2=4:3

ratio between radius will be equal to ratio blw diameters

hope it helps you
