Question

the ratio of circumference of two circle is 5:3 .What isthe ratio of their raddi​

Answer 1

Answer:

Mark it as brainliest

Yes

Step-by-step explanation:

circumference =2πr

c1/c2 = 5/3 = 2π r1/2πr2

thus r1/r2 = 5/3

Answer 2

Answer:

5:3

Long & Complicated Explanation:

Let circumferences be C1 & C2 and radii be r1 & r2

C1 = 2πr1

C2 = 2πr2

C1 : C2 = 5 : 3

(C1)/5 = (C2)/3

(2πr1)/5= (2πr2)/3

r1/r2 = 10π/6π = 5/3

r1:r2 = 5:3

for short explanation, refer to the other answer. DO NOT mark my answer brainilest.
