The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".
x²+y²-8x-6y+2 =0 -----(a)
(x-4)² = x² - 8x + 16
(y-3)² = y² - 6y + 9
Equation (a) can be rewritten as:
(x-4)² + (y-3)² + 2 - 16 - 9 = 0
(x-4)² + (y-3)² = 23
The coordinates for the center of the circle is: ( 4,3)
The radius is √23=4.8
Answer:
225
Step-by-step explanation:
i used a calculater and did 90 divided by .40
I’m not so sure i’m sorry
PQ = 2 units
height = 4 units
area = 2*4 = 8/2 = 4 square units
Answer:
B
Step-by-step explanation:
this equation is in the form of ax^2+bx+c
so a is 4, b is -9, and c is 8
