Question

How to solve this question If the circumference of a circle is reduced by 50percent then find the area which will be reduced by

Answer 1

Answer:

Step-by-step explanation:

Let the circumference of circle = 2*pi*r

If it is reduced by 50 % ==> 2*pi*r* (50/100)

                                      ===>pi*r

here pi is constant and only radius get reduced by 50%

so radius will become r/2

Area of circle = pi*r*r

Now the area of circle = pi*(r/2)*(r/2)

                                      = (1/4) pi* r*r

It wil be reduced by 25%
