Answer:
Center: (2,-1)
Radius: 4 units
Step-by-step explanation:
Equation of the circle in standard form is:
The radius of this circle is located at (-g, -f) and its radius is equal to:
The given equation of circle is:
Re-writing this equation in a form similar to the standard equation:
Comparing this equation with standard equation we can say:
g= -2
f = 1
c = -11
So, the center of the circle will be located at (-g, -f) = (2, -1)
And the radius will be = 
Thus the radius of the given circle is 4 units.

Step-by-step explanation:
16) 9y+2r If she bought 1 dog toy and 2 treats: 9(1)+2(2)= 13
17) 5n-3n= 2n
17-2+7= 22 Combine like terms
2n+22 Write out expression
2(8)+22= 38 Plug in 8.
Answer: 2n+22; 38
18) 5h^3 h represents the # of weeks; Find # of tickets sold in 3 weeks:h=3
5(3)^3 plug in 3
5(27) PEMDAS; Exponents first; 3*3*3= 27
Answer: 135
19) It is true
If d=2, 5(2)*5(2)*5(2)= (5*2)^3
10*10*10=(10)^3
1,000=1,000
Pythagorean theorem you times 40 by 2 then 9 by 2 then square root
