Question

the ratio of radii of two circle is 3:2 what is their circumference ?​

Answer 1

Answer:

the ratio of the circumference of circles is 3 : 2

Step-by-step explanation:

as the circumference of the circle is 2*π*r

so the ratio of two circles will be same as the the radius of circles

i.e.

C1/C2 = 2 * π * 3 / 2 * π * 2

C1 / C2 = 3 / 2
