Question

A circle has a radius of 18 and a center at (10,-9). Find the equation of the circle.

Answer 1

(x-10)²+(y+9)²= 324.

Explanation:

For this question, you will need to substitute these values into the equation of a circle:

(x-h)²+(y-k)²= r²

'h and k' represent the center points, and 'r' represents the radius.

This will result in:

(x-10)²+(y+9)²=324.
