Theo containers designed to hold water are side by side, both in the shape of a
OlgaM077 [116]

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

We have given that the shape of a

cylinder Container A has a diameter of 30 feet and a height of 18 feet.

diameter =30 feet and height =18 feet

Therefore

radius=\frac{d}{2} \\\\radius=\frac{30}{2} \ \\\\radius=15

What is the formula for volume of cylinder ?

volume =\pi r^2h

For cylinder A,

volume =\pi r^2h

volume =\pi (15)^218\\ \\V=12723.45 ft^{3}

Similarly for cylinder B,

h=19

radius

\frac{26}{2} =13feet

volume of cylinder B

volume =\pi r^2h\\\\volume =\pi (13)^2(19)\\\\volume =10087.65 feet^3

After pumping all of Cylinder  A into Cylinder B there will remain empty space in B

12723.45-10087.65=2635.8 feet^3

The percentage this empty space is,

of the entire volume is

\frac{2635.8}{10087.65} =0.261289

which is 26.12 %  when rounded to the nearest tenth.  

Therefore,

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

Fine the following when a=-2, b=4, c=7<br> 7b-12 over 2ac
iren [92.7K]
Hello!

You have to put the numbers in for the variables in the equation

\frac{7b - 12}{2ac}

Put the numbers in

\frac{7(4) - 12}{4(-2)(7)}

Combine like terms

\frac{28 - 12}{-56}

\frac{16}{-56}

The is is \frac{16}{-56} or about -0.29

Hope this help!
