Answer:
Option A 
Step-by-step explanation:
The volume of a cone is:

The volume of a cylinder is:

Both figures have the same height h and the same radius r.
The volume of the cylinder
We want to find the volume of the cone.
Then, we find r and h:

We simplify.

Then the product of
.
We substitute this in the cone formula and get:

A)
2, 4, 6, 8, *10
The fifth row contains 10 cans.
----------------------------------------------------
b)
2+4+6+8+10+12+14+16+18+20=110
-----------------------------------------------------
c)
2*Row=Number Of Cans
When Row=1, Number Of Cans=2.
When Row=5, Number Of Cans=10.
When Row=10, Number Of Cans=20.
The number is 3 because 3 multiplied by itself (3) is equal to 9.
