Answer 2

Given radius = 5cm.

We know that Area of circle = πr^2

= > (22/7) * (5)^2

= > (22/7) * 25

= > 550/7.

We know that circumference of circle = 2πr

= > 2 * (22/7) * 5

= > 220/7.

Now,

Required percentage = (πr^2)/(2πr) * 100

= > (550/7) * (7/220) * 100

= > 250%.

The answer is option - D

Hope it helps!
