<span>Skew lines exist in a
three-dimensional geometry. These are lines that are not parallel with each
other but do not intersect. They are lines that do not lie on the same plane or
non-coplanar. Hope this helps since there is no figure attached to the problem. </span>
2.) 
--> 
So y = -4.

Answer:
5:7
Step-by-step explanation:
Let the radius of first hemisphere be 'r' units
Let the radius of second hemisphere be 'R' units
2 x \piπ x r^2 / 2 x \piπ x R^2 = 25 / 49
r^2 / R^2 = 25 / 49
r / R = 5 / 7
the ratio of radii is 5:7.
