Question

`(x-4)^(2) ^+(y-3)^(2) =16`

Find the center and radius

(explanation please, I need help)

Answer 1

an equation for a circle has formula

(x-m)² + (y-n)² = r²

where (m,n) is its center

and r is its radius

so, the equation has center (4,3) and radius 4

the equation is derived from the pythagorean theorem
