I'm totally lost on this one, I keep getting similar problems wrong, the last equaled out to 4000/3 pi in.^3

Hey if psble could you attach the original diagram

ganeshie8 (ganeshie8):

I'm finding it a bit hard to relate the word problem to the picture that you have drawn

OpenStudy (anonymous):

Ok got you

OpenStudy (anonymous):

It wants me to find the volume, I even tried the V=4/3*3.14*r^3

Think of the given diagram as a small spherical fish tank, 10cm represents the center of top surface to the center of fish tank : |dw:1443067804228:dw|
