Question

X^2 +(y-1)^2=1 find the h,k find the radius of the circle find the intercepts and graph the circle

Answer 1

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

X^2+(y-1)^2=1

By looking at the expression we can see that:

k=1

h=0

and radius = 1

r^2 =1

r = √1

r=1

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

center = (h,k) = (0,1)

radius = 1
