Question

Which of the following points represents the center of a circle whose equation is (X - 5)2 + (y-4)2 = 25?

Answer 1

The correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).

The complete question is as below:-

Which of the following points represents the centre of a circle whose

equation is (X - 5)2 + (y-4)2 = 25?

A. (-5,-4)

B. (5,-4)

C. (-5,4)

D. (5,4)

What is a circle?

The circle is defined as the locus of the point traces around a fixed point called the centre and is equidistant from the out trace.

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

(x - 5)² + (y - 4)² = 25 ← is in standard form

We can see that the centre of the circle is (5,4) by comparing the equation with the standard form.

Therefore the correct answer is option D. The coordinates of the centre for the given equation of a circle is (5,4).
