Question

Write an equation of the circle with center (5, 2) and diameter 12.

Answer 1

`(x-5)^2 + (x-2)^2 = 6^(2)`

Explanation:

Standard equation of a circle is

`(x-x_(0))^2-(y-y_(0))^2 = r^2\\r=(1)/(2)d`

As the radius is half of the diameter we can divide 12 by 2 to get a radius, then we can input values into this equation.
