Question

the ratio of radii of two circle exceeds 5:3find the ratio of their cicumferences​

Answer 1

Answer:

let the r1 is x then and r2 is 3r1/5

ok

then the circumference are 2πx:2π3x/5

then

ratio of circumference is 5:3

ok

follow

me

guys

Answer 2

Step-by-step explanation:

Let the radii of the circles be 5r1 and 3r2

• So, 2*22/7*5r1=2*22/7*3r2
• =5r1=3r2
• =r1/r2=5/3
• =r1:r2=5:3
• so ratio of circumference would remain the same.
