Question

If circumference of a circle is decreased by 50% then area of circle is decreased by... Find solution

Answer 1

Answer:

Step-by-step explanation:

Let the circumference of circle be $C$

Given that circumference is decreased by $50\%$

Thus, new circumference $=0.5C$

We know, Circumference is given as

$C = 2 \times pi \times R$

Where, R = Radius

When circumference  = 0.5C

We have

[tex]C' = 0.5 (\,2 \times pi \times R)\\\\ C' =
