Answer 2

Hey friend!!

To find the Area Of Circle when the  Diameter is given then you can do 2 methods:

1) You can divide the diameter by 2 and then substitute that answer in this formula: Area of Circle= $\pi r ^{2$ 
Where you should put your answer in the place of r.


2) You can directly substitute your diameter in this formula:
Area of Circle= $\frac{1}{4} \pi d^{2}$

And you will Get both the answers equally same!

Hope This helps!!
