Question

If the ratio of diameters of two circles is 3:5 find the ratio of their circumferences

Answer 1

Answer:

3:5

Since 2π is a constant

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Ratio of diameters = 3:5

Let the diamenters 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!!

Hope it helps!!
