What is the radius of a circle with the equation (x − 3)2 + (y − 7)2 = 9?

A) 3
B) 4.5
C) 6
D) 9

Respuesta :

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 3)² + (y - 7)² = 9 ← is in standard form

with r² = 9 ⇒ r = 3 → A
