ANSWER

EXPLANATION
The equation of the circle with radius r and centre (a,b) is given by

The radius is

We need to determine the center of the circle from the given equation of another circle, which is,

We complete the square to obtain,





The centre of this circle is (4,3)
Hence the center of the circle whose equation we want to find is also (4,3).
With this center and radius 2, the required equation is,

Therefore the correct answer is C.
So the question here is just simply what percentage is 10 out of 50 correct? You would basically just do 10/50 times 100 which will give you 20 percent as your answer.
3/5=q/10
multiply both sides by 5 or cross multiply i fyou like
30/5=10q/10
6=1q
6=q
