The circle below is centered at the origin and has a radius of 5 what is it’s equation
Accepted Solution
A:
Answer:x^2 + y^2 = 5^2or x^2 +y^2 = 25Step-by-step explanation:The equation of a circle is usually written in the form(x-h)^2 + (y-k)^2 = r^2Where (h,k) is the center and r is the radiusThe center is at the origin so (h,k) = (0,0) and the radius is 5 so r=5x^2 + y^2 = 5^2or x^2 +y^2 = 25
