There are 12 different pizza toppings, and Arturo must rank his top 6 in order. How many different possible rankings are there?
1 answer:
The first ranking can take 12 ways.
The second ranking can take 12 - 1 = 11 ways
The third ranking can take 12 - 2 = 10 ways
and so until the six rankings are performed.
The product of the six rankings is
12*11*10*9*8*7 = 665,280.
This result is given by the permutations of 6 objects out of 12. It is given by
which yields the same result.

The space is inside the cylinder but outside the cone is 200π cubic FT or 628.32 cubic FT.
<h3>What is a cone?</h3>It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
We know the volume of the cylinder is given:
r = 10/2 = 5 FT
h = 12 FT
V = 300π cubic FT
Volume of the cone:
v = 100π cubic FT
Space is inside the cylinder but outside the cone = 300π - 100π
= 200π cubic FT
= 628.32 cubic FT
Thus, the space is inside the cylinder but outside the cone is 200π cubic FT or 628.32 cubic FT.
