Question

if the ratio of two radii of two circle is 7:15 the ratio of their circumference.

Answer 1

Step-by-step explanation:

no idea please and what is radii

Answer 2

Answer:

ratio of circumference of two circle is 7:15

Step-by-step explanation:

ratio of radii = r1 : r2

ratio of circumference =( 2 * pi * r1 ) : (2 * pi * r2)

Cancelling common terms

ratio of circumference = r1 : r2

ratio of radii and circumference are equal.

Check

ratio of radii = 7 : 15

ratio of circumference = 2*22/7* 7 : 2*22/7*15

Cancelling common terms

ratio of circumference = 7:15
