Assume that the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder. base on this assumption, the volume of the flask is

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

6mm^3 or .6cm^3

6     6   6

factor trees are nice.
