Answer:
x^2 + y^2 = 5^2
or x^2 +y^2 = 25
Step-by-step explanation:
The equation of a circle is usually written in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
The center is at the origin so (h,k) = (0,0) and the radius is 5 so r=5
x^2 + y^2 = 5^2
or x^2 +y^2 = 25
Answer:
x² + y² = 25
Step-by-step explanation:
(x - h)² + (y - k)² = r²
Center ( h⁰, k⁰)
radius = 5/r
(x - 0)² + (y - 0)² = 5² ⇒ x² + y² = 25
This will be your answer : x² + y² = 25
