Answer 1

Answer:

5:3

Step-by-step explanation:

given ratio of radio is 5/3

r1/r2 =5/3

Let r1=5@,re=3@

ratio of their circumference is (2×(22/7)×5@)/(2×(22/7)×3@)

that is 5/3

Answer 2

Answer:

2.236/1.732

Step-by-step explanation:

the ratio of the areas is 5/3

therefore pyr1^2/pyr2^2=5/3

threfore r1^2/r2^2=5/3

therefore r1/r2= root5/root3

ratio of circumference= 2pyr1/2pyr2= r1/r2= root5/root3= 2.236/1.732
