Write -12 in the improper fraction form.
nydimaria [60]

Answer:

\frac{-12}{1}

Step-by-step explanation:

An Improper Fraction has a top number larger than (or equal to) the bottom number.

To convert a whole number -12 into an improper fraction we can divide the whole number by one to turn it into a temporary fraction.

\frac{-12}{1}

Also we could multiply and divide -12 by another number greater than one, for example:

\frac{-12*2}{1*2} = \frac{-24}{2}

There are several ways we can write -12 in the improper fraction form.

Find volume of cylinder <br><br> Show work
zloy xaker [14]

For this case we have that by definition, the volume of a cylinder is given by:

V = \pi * r ^ 2 * h

Where:

A: It is the radius of the cylinder

h: It's the height

We have according to the data that:

r = \frac {34} {2} = 17 \ m\\h = 27 \ m

Substituting in the equation we have:

V = \pi * (17) ^ 2 * 27\\V = \pi * 289 * 27\\V = 24501.42\ m^3

ANswer:

V = 24501.42\ m^3
