PLEASE HELP! Find the height of a cylinder with a surface area of 108 pi square meters. The radius of the cylinder is twice the
Naily [24]
Assuming the cylinder is closed at both ends 
Surface area = 2 pi r^2 + 2 pi r h  = 108

now h = r/2 so we have:-

 2pi r^2 +  pi r^2= 108

 3 pi r^2   = 108
r^2 = 11.459
r =  3.385 
so the height h = 1.693 m to nearest thousandth

If you have 9/10 of a pound of granola how many 1/5 pound bags can you fill ?
Lostsunrise [7]

Answer:

4

Step-by-step explanation:

1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.
