The volume of a cylinder is PiR^2H.
We have the radius and height, so we can answer this.
Pi = 3.14
R = 11
H = 18
3.14 x 11^2 x 18.
Your answer is 6838.92 inches.
Answer:
- $5.5 per pound
- 
Step-by-step explanation:
Given
$11 for 2 pounds
Solving (a): Cost per pound
This is calculated by dividing $11 by 2 pounds


Hence, the cost per pound is $5.5 per pound
Solving (b): Represent as an equation.
If 1 pound costs $5.5 (as shown in (a))
Then
x pounds costs $5.5 * x


This cost is represented with y
