Answer: 2 A=pi x radius squares so 12.56/3.14159 is the radius squared, Now to find the radius take the square root of that. So we have r squared is 3.9997 or very close to 4 so the radius is very close to 2. We can say it is two in this case we say it is two since we are only dealing with hundreds and 3.9997 rounds to 4

Area = Pi*r*r3.14*20*20=1256 aboutC=2*pi*r2*3.14*20=125.6 about
What is the radius of a circle that has a 190 degree central angle and a secor area of 662.89?
assuming Pi is 3.14159 your answer is 19.994938227 continues Basically 20 or 19.995 662.89 is 190/360th of the total area total area was therefore 1256 A = Pi r2 So 1256 divided by Pi then find the square root of that number
