A circle has a radius of 9 units and a center located at (-5, 2) on a coordinate plane.
Which of the following equations represent this circle?
A (x - 5)2 + (y + 2)2 = 81
B
Kx + 5)2 + (-2)2 = 81
(x - 5)2 + + 2)2 = 3
(x + 5)2 + (-2) = 3

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

Given that:-

A circle has a radius of 9 units and a centre located at (-5, 2) on a coordinate plane.

The equation of the circle will be:-

( x - h )² + ( y - k )² = r²

( x + 5 )² + ( y - 2 )² = 81

Therefore the equation of the circle will be equal to ( x + 5 )² + ( y - 2 )² = 81
