Question

if the ratio of diameter of two circle is 3:5 find the ratio of the circumference

Answer 1

Answer:

Ratio of diameters = 3:5

Let the diameters be 3y and 5y.

Circumference of circle 1 = 2πr= (2r)π = dπ = 3yπ

Circumference of circle 2 = 2πr = πd = 5yπ

Ratio of circumference of circles = 3yπ/5yπ = 3/5 = 3:5

The answer is 3:5!!
