Answer:
(x - 2)² + (y - 0)² = 5²
Explanation:
the standard form of equation of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center,
r is the radius, and
(x, y) are the co-ordinates
according to the question:
center, (h, k) = (2, 0)
co-ordinates of a point (x, y) = (2, 5)
(2 - 2)² + (5 - 0)² = r²
0 + 5² = r²
r² = 25
r = √25 = ±5
thus, the standard form of equation of a circle is,
(x - 2)² + (y - 0)² = 5²
