Wallsare 3 inches thick
diameter is 20 feet, find real diametter
legnth is 50 feet, find real legnth
minus 6 inches from each measurement since that is not included
20ft-6in=19.5ft
50ft-6n=49.5ft
we have a cylinder and a 2 hemispheres
2 hemispheres=1 sphere
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
r=d/2
r=19.5/2=9.75
h=49.5
Vcylinder=49.5*pi*9.75^2=14783.058738886 ft^3
Vspere=(4/3)pi9.75^3=388419466778 ft^3
add them
Vcylinder+Vspher=14783.058738886+388419466778 ft^3=18665,478205664ft^3
V=18665,478205664 ft^3
times 7.48 to find gallons
Vingallons=139617.77697837 gallons
I think the answer is 13.5 square units.
Answer:
5 batteries.
Explanation:
"How many batteries lasted more than 5 1/2 hours?" which means it's counting not only 5 1/2, but 5 3/4 and 6 1/4
The graph is missing. So is the set of data point values. However, I can assume that as the temperature goes up, then so does the sale of ice cream. It's not a perfect relationship, but there is a strong positive correlation between the two variables.
A positive correlation means that as one variable increases, so does the other. Also, it means that if one variable decreases, then the other variable decreases as well. The two variables move in the same direction together.
