Question

The circumference of two circle are in the ratio 5:6, find the ratio of their radius.

Answer 1

Answer:

Step-by-step explanation:

Circumference of circle = 2pieR

let R1 be the radius of 1st circle and R2 be the ratio of second.

On calculating the ratio ... 2 x 3.14 x R1 / 2 x 3.14 x R2 = 5/6

So after cancelling we can see that R1/R2= 5/6

So the ratio of radius is also 5:6

Answer 2

Answer:

5:6

Step-by-step explanation:

let the radius of the circles be R1 and R2

R1=5

R2=6

Circumference = 2*pie*R

Ratio of the circumferences = 2*pie*R1/2*pie*R2

Here, 2 and pie get cancelled leaving behind R1/R2

and hence it becomes

5/6

therefore, the ratio between the circumferences of the circles is also 5:6.
