Why was the volume of your fountain smaller than the volume of the ideal sphere? discuss a more accurate method for approximating the volume of the spherical slab other than using just cylindrical slabs. discuss in two to three sentences.
fountain volume: 197.035 cm³
volume of sphere: 525.33 cm³

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

irrational, cannot

9x

i think the answer is 90 hope this
