In the figure shown, AB is a diameter of the circle and O is the center of the circle. If A = (3, 4), then what is the circumference of the circle?
(A) \(3\)
(B) \(4\)

1
distance OA = \(\sqrt{4^2+3^2}\) = \(\sqrt{25}\) = \(5\)
Circumference = \(2*pi* 5\) =\(10*pi\)
So the answer is E
Circumference = \(2*pi* 5\) =\(10*pi\)
So the answer is E
