## anonymous one year ago A spherical fish bowl is half-filled with water. The center of the bowl is C, and the length of segment AB is 20 inches, as shown below. Use Twenty two over seven for pi. A sphere with diameter 20 inches is drawn. Which of the following can be used to calculate the volume of water inside the fish bowl?

1 over 24 over 322 over 7(203) 1 over 24 over 322 over 7(202)(10) 1 over 24 over 322 over 7(103) 1 over 24 over 322 over 7(102)(20) @peachpi

I thought it would be the third option as

can you take a screenshot of the choices. It's kind of hard to tell what the exponent and fractions are. I think it's asking for half the volume of the sphere since it's half full of water. If the volume of the sphere is $V=\frac{ 4 }{ 3 }\pi r^3$ Then half of that is $V = \frac{ 2 }{ 3 }\pi r^3$

oh ok I see, they don't want you to use pi. so it looks like the 3rd one is correct
