## 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) @calculusxy

$V = \frac{ 4 }{ 3 }\pi r^2$

Our diameter is 20 inches, and radius is always half of diameter. Thus, the radius is 20/2 which equals .... ?

r=10

6. calculusxy

yes now plug those info into the formula given

7. anonymous

so V=4 over 3 pi10^2??

8. calculusxy

yes $\frac{ 4 }{ 3 }\pi (10)^2$ $\frac{ 4 }{ 3 }(\frac{ 22 }{ 7 })10^2$

9. calculusxy

Remember that pi in here means 22/7

disregard that comment

But that isn't any of the options given

This looks like a complex question especially with the multiple choices.
