(a) 2
(b) 2:r
(c) r: 2​

Answer:

we know that area of circle is pi×r²

and circumference of circle is 2×pi×r

so ratio is

pi×r²/2×pi×r

r:2

Answer 2

The ratio of circumference and area of a circle is 2:

$\frac{area \: of \: circle}{circumference} = \frac{ {\pi}r^{2} }{2\pi \: r}$

= r/2

= r: 2

option (c) is correct
