Question

10. Find the standard equation of the circle having the given center and radius.

Answer 1

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 is the radius

here (h, k) = (3, 5) and r = , hence

(x - 3)² + (y - 5)² = ( )², that is

(x - 3)² + (y - 5)² = ← equation of circle
