Question

The ratio of the radii of two circles is 5:3. Find the ratio of their circumferences.​

Answer 1

Answer:

5:3

Step-by-step explanation:

The circumference of a circle is 2×(3.14)× r, where t is the radius of the circle

ratio of radii = r1/r2 = 5:3

$ratio \: of \: cicumfreces \: = \frac{2\pi \times r1}{2\pi \times r2}$

which is equal to,

$\frac{r1}{r2}$

Therefore the ratio of the radii is equal to the ratio of the circumference
