I'd be more than happy to do all of that, but I can't even start
until I see YOUR picture of the problem. That will show me
if circle-P and circle-q are overlapping, just touching, separate
from each other, same size, different sizes, their radii, and where
the points J and K are. THOSE are the little things I need to know
in order to get started.
You want to know the distance between J and K, but you haven't
given us one single distance or size of anything in the problem ...
nothing at all to work with. That right there makes it impossible.
Surface area define or calculate the exact space that each face of the said shape is taken up while the volume is how much space is inside the said object. The area use the unit that is squared because it only measured 2 face in the shape while the volume measures 3 faces in the object. an example of an area is a card board area, while the volume is the glass of water.
The pattern for this is least to greatest
