What is the center of the circle with the equation x2 + y2 +4x-8y+11 = 0 ?

c

Step-by-step explanation:

(-2,4)

Step-by-step explanation:

You do this by completing the square for x and y.

x^2 + 4x + (4/2)^2 +y^2 - 8x + (-8/2)^2 = - 11 + 4 + 16

(x + 2)^2 + (y - 4)^2 = 9

The center should be (-2,4)

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

answer: 2530

hope this
