Answer:
Step-by-step explanation:
Volume of cylinder = π times r^2 times h (height)
8,685.9 = π times r^2 times h
To find the radius, divide the diameter by 2.
19.2 / 2 = 9.6
8,685.9 = 3.14 x 9.6^2
3.14 x 9.6^2 = 289.38 (estimated)
8,685.9 = 289.38
Divide 289.38 by 8,685.9.
289.38 / 8,685.9 = 0.033316064

Answer:
$13.20 or $2.20
Step-by-step explanation:
Since percents are decimals, we can figure out the tip by multiplying the total by the decimal percent.
11 x .20 = 2.2
Now the answer depends on what you need the answer to be. if you need the total, it's $13.20.
If you need the tip, it's $2.20.
There are many different ways to figure this out but may I ask you one question....do you know whether the two legs are congruent or just the right angle?
