Answer:
The missing dimension, radius = 6.00 m
Step-by-step explanation:
We are given the following things:
Height of cylinder, 
= 15 m
Radius of cylinder, 
m (Labelled as 
)
Volume of cylinder, 
Please refer to the image attached for the dimensions of cylinder as given.
We know that the volume of a cylinder can be given as:
Where 
is the radius of cylinder
is the height of cylinder
Putting the values of 
:
Hence, The missing dimension, radius = 6.00 m
You use the quadratic formula:
2x {}^{2} - 3x = 5
2x {}^{2} - 3x - 5 = 0
x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}
x = \frac{3 + - \sqrt{49} }{4}
x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}
x = \frac{5}{2} \: and \: x = - 1
This is how I would do it:
-8x=28-4y divide the entire equation by 4
-2x=7-y Put y back on the left and put x on the right
y=7-2x.
Essentially look at your formula sheets, Take notes on your assessment questions and you should be fine.
