Hey!
Let's simplify the expression
sum = +
- The term "sum" is used when adding. Therefore, it is equal to "+".
8 times a number and 2 = 8x + 2
- 8 is equal to 8. The term "times" is used when multiplying. Therefore, it is equal to "×". "A number" is a variable. A variable can be any letter. In this case, I have made it "x", which is commonly used.
That gives you: 8x + 2
We can use formula of volume of cylinder to calculate volume of silo.

Plug the given values of radius r=7 ft and height h= 33 ft



So the required volume of silo is [tex] 1617 \pi [\tex]
0.47619047619 and just round so it'll be 0.48
Answer:
the blue one but not sure
Yes, 90° is supplementary and 180° is condemnatory.
