Answer:
D
Step-by-step explanation:
If you substitute the radius, 10, and the center of the circle, the origin (also known as (0,0) into the equation of a circle, you should get: ![(x - 0)^{2} + (y - 0)^{2} = 10 ^{2}](https://tex.z-dn.net/?f=%28x%20-%200%29%5E%7B2%7D%20%20%2B%20%28y%20-%200%29%5E%7B2%7D%20%20%3D%2010%20%20%5E%7B2%7D%20)
Multiplying this out should leave you with D as your answer.
