Question

This circle is centered at the origin, and the length of its radius is 10. What is

the circle's equation?
A. x+y=10
B. x¹° + y¹° = 100
C. X²+ y² =10
D. X² +y²=100

Answer 1

D

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)`

Multiplying this out should leave you with D as your answer.
