Answer 2

Answer:

√15

Explanation:Area of circle=πr²

area of circle no.1=πR²and area of circle no.2=πr²

from the question,

πR²=15πr²;

therefore,R²=15r²;

R²÷r²=15;R÷r=√15.

circumference of a circle =2πr

circumference of circle no.1=2πR and circumference of circle no.2=2πr

ratio of their circumference=2πR/2πr=R/r=√15.
