Answer:
1815 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the diameter =22
so the radius is d/2 = 22/2 =11
V = pi (11)^2 (15)
V = pi1815
V = 1815 pi cm^3

Answer:
This question is impossible! For two different variables, we need two different equations. Without that, there is no hope! :)
Answer:
32.4 $
Step-by-step explanation:
25% off means he is paying 75% of the original price
Original price = 100%
75%=0.75=3/4
3/4 of 40 is 30
Apply 8% tax on amount of 30$ and add calculated value to 30$.
OR: you can think of 30 $ as 100%. You have to add 8% tax--. now you have 108%
108%=1.08
1.08*30=32.4
