What are the center and radius of the circle defined by the equation x2 + y2 -6 x + 10y + 25 = 0
2 answers:
Answer:
(3,-5), radius 3
Step-by-step explanation:
To determine the center points and the radius of the circle, we can either graph the equation or write it in a form where the center and the radius can be easily be seen. For this, we use the second method. The form should be: (x - h)^2 + (y-k)^2 = r^2 (h,k) represent the center and r the radius We do as follows: <span>x2 + y2 -6x + 10y + 25 = 0 </span>x2 -6x + y2<span> + 10y = - 25 x2 - 6x + 9 + </span> y2 + 10y + 25 = -25 + 9 + 25 = 9 (x - 3)^2 + (y + 5)^2 = 3^2 Therefore, the center is at ( 3,-5) and the radius is 3 units.

Answer:
72 square units
Step-by-step explanation:
Identify the height Identify the length Multiply those two together That is your answer H = 9 units
L = 8 units
A = H × L
A = 9 × 8
A = 72 square units
