B. 4.
You can get this by setting them equal to each other and getting all of the x terms to one side. Then get the number values to the other and divide the coefficient away.
Answer:
x² + y² = 6.25
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.
From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so
( x – 0)² + ( y - 0)² = (2.5)²
x² + y² = (2.5)²
x² + y² = 6.25
