Question

the area of a circle of radius 5 cm is numerically what per cent of its circumference

Answer 1

The answer is 250%

Provided the question expects you to show what percent of the circumference is the area of a circle, we can show it as follows;

Required Answer in percentage = ( Area / Circumference ) x 100
= ( (π x r²) / (2π x r) ) x 100

Given that the radius, r = 5 cm

So, Required Answer in percentage
= ( (25π) / (10π) ) x 100
= (5 / 2) x 100
= 250%
