Question

NEED HELP! Which equation represents a circle with a center at (-5,5) and a radius of 3 units?

A.
(x − 5)2 + (y + 5)2 = 3
B.
(x − 5)2 + (y + 5)2 = 9
C.
(x + 5)2 + (y − 5)2 = 3
D.
(x + 5)2 + (y − 5)2 = 6
E.
(x + 5)2 + (y − 5)2 = 9

Answer 1

Equation of the circle is (x + 5)² + (y - 5)² = 9

Step-by-step explanation:

• Step 1: Given center is (h, k) = (-5, 5) and radius is 3. Equation of a circle is given by (x - h)² + (y - k)² = r²

Equation is (x - -5)² + (y - 5)² = 3²

⇒ (x + 5)² + (y - 5)² = 9

Answer 2

Answer:

(x + 5)² + (y - 5)² = 9
