Question

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 for pi. Which of the following can be used to calculate the volume of water inside the fish bowl?

Answer 1

I found the picture of the bowl.

AB is the diameter of the sphere.

So the radius is 20in / 2 = 10 in

And the volume of water is half the volume of the sphere.

=> V of water = (1/2)* (4/3) π (r^3)

Also, this problems asks to use 22/7 as approximation of π.

=> V of water = (1/2) (4/3) (22/7) (10in)^3 = 2,095 in^3

Answer: (1/2)(4/3)(22/7)(10in)^3 = 2,095 in^3
