Question

Write the equation of the circle centered at (0,1) with radius 15.

Answer 1

Answer:

$x^2+(y-1)^2=225$

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

$(h,k)=(0,1)\\r=15\ units$

substitute

$(x-0)^2+(y-1)^2=15^2$

$x^2+(y-1)^2=225$
