to find the area of a whole circle, use the formula Area = Pi * (Radius)^2
where Pi is approximately equal to 3.14.
so the area of the circle with radium = 4 m, is 16*Pi = 50.24 m^2;
to find area of a quarter of this circle, divide the total area by 4
to get 4*Pi= 12.56 m^2
First, find the whole area.
A = πr²
A = π(4)²
A = 50.2655
Then take 1/4 of it. 12.5664 m² ■

If the radius of a circle is doubled what happens to the area?
It quadruples. The area of a circle is Pi (about 3.14159) times the radius squared. So if you double the radius (say from 2m to 4m), you area will change from 4*Pi to 16*Pi (4 times what it was originally).
