Question

r: (h, k) = (0, 0), r = 4
Find the equation of the circle in standard form for the given center (h, k) and radius

Answer 1

Do you know what the standard form of a circle looks like?

Answer 2

yes please

Answer 3

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

Answer 4

\[(x−h)^2+(y−k)^2=r^2\]

Answer 5

replace h,k,r and solve

Answer 6

Answer 7

so, here (x-0)^2 + (y-0)^2 + 4^2
=> x^2 + y^2 = 16 is the required equation @Hannah777
