What is the slope of the cake?

Given :
measures 2ft. high in the center 
diameter of the bottom tier is 12 inches

Solve:
Since feet and inches are in different unit, we are going to convert 2 feet to inches. 12 inches = 1 foot. Therefore 2ft. = 24 inches

Formula of the slope 
{{{m = (rise)/(run)}}}
The cake is 24 inches high and 6 inches from the center (radius=6).

{{{m = 24/6}}}
{{{highlight (m=4)}}}
