Answer:
m = -8
Step-by-step explanation:
Use the slope formula: 

m = -8
2-1/4
2/1=8/4 Multiply top and bottom by 4
8/4-1/4
7/4
1 3/4
Area of the triangle base: (1/2)*3.3*x
area of the cone base: pi*3*3
they are equal, so 9pi=(1/2)*3.3x
x=17.1
THE 5 IDENTICAL SHELVES WOULD have to be 76 because if you take 400 - 20 (because that left over) you get 380/5 you get 76 and to check your work you do 5x76=380+20 you get 400 so 76 is you answer
