Question

A spherical fish bowl is half-filled with water. The center of the bowl is C, and the length of segment AB is 12 inches, as shown below. Use 22/7 for pi.



What is volume, in cubic inches, of water inside the fish bowl?

Answer 1

that's easy... calculate the volume of the bowl with 4/3*pi*r^3
whereby r stands for the radius (1/2 of segment AB)
since half of the bowl is filled, 1/2*volume

Answer 2

ok give me a minute to solve ;)

Answer 3

so the new formula will be 4/3*3.14*12 or 6 for radius?

Answer 4

6.. I already said that is was the radius which is 1/2 of the segment AB.. but you shouldn't forget the ^3 of the radius

Answer 5

I got 905.14

Answer 6

should be correct if you followed the instructions :P

Answer 7

alright! thnx so much!

Answer 8

though.. I'm not sure if you need to convert inches to meters before you can use the equation stated before.. I think it is necessary...

Answer 9

no, its asking in inches ;)

Answer 10

yes but you use several numbers and pi... you don't just use parameters in inches..

Answer 11

but werent they all in inches?

Answer 12

no.. pi doesn't have a have unit and neither does 4/3... which usually means that you can only use SI-units in the calculations.. I'm not sure on this though.. as I mentioned in an earlier question, here we aren't so stubborn that we keep on using useless units like ft and inches XD we use meters for everything which makes it a lot easier during any math or physics problem..

Answer 13

I'f I were you I would try it out.. shouldn't be that much trouble to do the calculations in meters as wel.. Butt it's sleepy time over here so if you want more answers from me you gotta wait until tomorrow :D Nighty Night

Answer 14

thanx!and hav a great night! ;)
