Question

The ratio between circumference and diameter of a
circle is
(i) 1:1 (ii) r:π

(ii) 1:2 (iv) 2:1​

Answer 1

Answer:

Step-by-step explanation:

see, they asked ratio,

formula of circumference = 2 pi r

formula of diameter = 2r

2 pi r/2r (2 and r gets cancelled)

therefore answer we get is Pi

the ratio of circumference and diameter is always = pi irrational number :)

Answer 2

Answer:

π : 1

Step-by-step explanation:

circumference of circle = 2πr

diameter = 2r

ratio:-

2πr : 2r

[ 2 and r get cancelled]

∴ π : 1 is the ratio
