<em><u>The equation for the product of -2 and -30 gives 60 is:</u></em>
<em><u>Solution:</u></em>
Given that, The product of -2 and -30 gives 60
We have to write the sentence as equation
It includes operations such as addition, subtraction, multiplication and division.
From given statement,
The product of -2 and -30 gives 60
Here, "product" means multiplication
Therefore, -2 multiplied with -30 gives 60
Which is written as equation as,
Thus the given sentence is translated into equation
Area of a cylinder is the area of the top + the area of the bottom + the area of the wrap-around (lateral)
top: pi*r*r=81pi
bottom: 81pi
lateral: 2pi*r*h=18pi*h, h is unknown, but you don't have to solve it.
add them up: 81pi +81pi + 18h*pi=1850
pi*h=(1850-162pi)/18, (plug this in the volume formula below.)
volume of a cylinder: the area of the base × the height =81pi*h
volume=81[1850-162pi)/18]
use your calculator: V=6036
please double check my calculation by yourself.
Hundred thousand because there is a zero in that spot
