Answer:


\displaystyle {\pi}r^2 = A

Step-by-step explanation:

To find the area of any circle, you multiply π by the square of its radius. If at ANY point the circle gives you a diametre, split it in half BEFORE squaring it. Now, in case you have not received the information you were looking for, π is represented as
\displaystyle 3,1415926536...\:.So, whenever you need to find the area of a circle or volume\area of ANY OTHER three-dimensional figure, like a sphere, use the next three desimal-plase digits to get a more accurate measure [3,14159].

I am joyous to assist you at any time.

Hello.

This is the formula for the area of a circle:


\mathrm{A=\pi r}^(2)

Where

A stands for area

r stands for radius

π stands for pi (3.14...)

Therefore, the area of a circle is


\mathrm{A=\pi r}^(2)

I hope it helps.

Have a nice day,
