diameter or radius?
4m
12.56m or 4pi(m)
Area required = 130/360 x 16 pi ie 18.15 sq m
The answer will depend on which one of the two numbers is the radius (or diameter, or circumference) and which is the height. Since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
A circle with a radius of 4m has a circumference of 25.133m.
diameter or radius?
4m
Circumference = diameter x pi = 4m x 3.1416 = 12.566m (approx)
The circle has an area of 16pi m2 or approximately 48m2.
12.56m or 4pi(m)
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).
