Question

The circle below is centered at the point (4, 3) and has a radius of length 5.

What is its equation?

Answer 1

`(x-4)^(2) + (y-3)^(2) = 5^(2)`

Explanation:

Equation is circle is given as

`(x-x_1)^(2) + (y-y_1)^(2) =r^(2)`

Here
`(x_1. y_1)=(4, 3)` and
`r=5`

Equation of circle with center at (4, 3) and radius 5 can be written as

`(x-4)^(2) + (y-3)^(2) = 5^(2)`
