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
I'm finding it a bit hard to relate the word problem to the picture that you have drawn
the picture i drew is pretty much it.
Ok got you
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|
They gave you surface area of the top surface : \(576\pi\) Say, the radius of top surface is \(r\) : |dw:1443067992574:dw|
\[\pi r^2 = 576\pi\] solve \(r\)
Yes, the radius of top circular disk surface is \(24\) : |dw:1443068220493:dw|
Next, see if you can find the radius of sphere : |dw:1443068276532:dw|
would I substitute 24 as r into the same equation?
do you see a right triangle with sides \(10, 24, R\) ? you need to setup an equation and find the value of \(R\)
which equation would I use? A=1/2 bh? sorry....
when you see a right triangle, you should think of "pythagoras theorem"
yes take square root
@ganeshie8 What do I do next?
so \(26\) is the radius of sphere
use volume formula of sphere and finish it off
I get a huge number 73584.85
