Answer:
Radius = 6.46 meters
Height = 1.46 meters
Step-by-step explanation:
The volume of a cylinder = πr²h
In the above question, we were given
r = (x + 5) meters
h = x meters
Volume = 192 cubic meters
Hence,
192 = π × (x + 5)² × x
192 = π × (x² + 10x + 25) × x
192 = π × (x³ + 10x² + 25x)
Divide both sides by π
192/π = x³ + 10x² + 25x
61.115498147 = x³ + 10x² + 25x
x³ + 10x² + 25x - 61.12
This Quadratic equation is a polynomial
x = 1.46119
From the above:
Radius = (x + 5)meters
Radius = 1.46119 + 5 = 6.46119 meters
Approximately to 2 decimal places = 6.46 meters
Height = x meters
Height = 1.46119 meters
Approximately to 2 decimal places = 1.46 meters
Answer:
17852.5$
Step-by-step explanation:
I already answer this in another part, but here it is againa:
In this case, all you need to do is sum all the amounts and take out the down payment of 2500$
First, the car of 18,500 with the 6.5% sale tax, it would be:
18,500 * (6.5/100) = 1202.5$
18500 + 1202.5 = 19702.5$
Now the charge and fees:
450+155+45 = 650$
Then:
19702.5 + 650 = 20352.5$
Finally, the down payment:
20352.5 - 2500 = 17852.5 $
They are variables. They stand in for different numbers in a problem. for example) a=12
Answer: [0,3]
The line is going up from left to right between 0 and 3 on the x-axis. We use a closed bracket because it is a open circle.
18
First you want to change the 20% into a decimal which is .20
Next you want to multiply 90 by .20 because that will give you the answer for 20% of 90
90x.20=18
Hope that helps
