Step-by-step explanation:

The area A of the tire in contact is 7"×5" = 35 sq inches and we know that each tire has a pressure of 30 psi so the weight of the car in tons is

$W = \dfrac{APN}{2000} = \dfrac{(35\:\text{in}^2)(30\:\text{lbs/in}^2)(4)}{2000}$

$\:\:\:\:\:= 2.1\:\text{tons}$

What is x, if the volume of the cylinder is 768pi rcm3?

AVprozaik [17]

let's recall Cavalieri's Principle, <u>solids with equal altitudes and cross-sectional areas at each height have the same volume</u>, so even though this cylinder is slanted with a height = x and a radius = 8, the cross-sectional areas from the bottom to top are the same thickness and thus the same area, so its volume will be the same as a cylinder with the same height and radius that is not slanted.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=8\\ h=x\\ V=768\pi \end{cases}\implies 768\pi =\pi (8)^2(x)\implies 768\pi =64\pi x \\\\\\ \cfrac{768\pi }{64\pi }=x\implies 12=x$
