Question

create a general equation to model the number of cups of juice needed to fill a semi-spherical bowl with a radius of 'r' inches given that each cup of juice contains approximately 14 cubic inches.

Answer 1

To model the number of cups of juice needed to fill a semi-spherical bowl with a radius of 'r' inches, we first need to find the volume of the bowl.

The volume of a sphere is given by the formula:

V = (4/3)πr³

Since we are dealing with a semi-sphere, we divide the volume by 2:

V = (2/3)πr³

Now, we can convert the volume to the number of cups needed by dividing it by the volume of each cup of juice (approximately 14 cubic inches):

Cups = V/14

Therefore, the general equation to model the number of cups of juice needed to fill a semi-spherical bowl with a radius of 'r' inches is:

Cups = [(2/3)πr³]/14
