Starting with the definition 1.00in. = 2.54 cm, find the number of kilometers in 7.00mi . Please describe conversions.

ella [17]

The answer is 11.265408 km.

To calculate the number of kilometers, we will use several conversions:
A) 1 mi = 63,360 in
B) 1 in = 2.54 cm
C) 1 cm = 0.00001 km

A) 1 mi = 63,360 in
7 mi = 63,360 in · 7 = 443,520 in

B) 1 in = 2.54 cm
443,520 in = 2.54 cm · 443,520 = 1,126,540.80 cm

C) 1 cm = 0.001 km
1,126,540.80 cm = 0.00001 km · 1,126,540.80 = 11.265408 km

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad r=radius=\frac{diameter}{2}\\\\
-----------------------------\\\\

\begin{array}{lcccclllll}
&radius&\$&Cmfc&\frac{Cmfc}{\$}\\
&---&---&-----&-----\\
\textit{Baby Bear}&6&10&2\pi \cdot 6&\frac{2\pi \cdot 6}{10}\\\\

radius=\frac{18}{2}=9
\end{array}&17&2\pi \cdot 9&\frac{2\pi \cdot 9}{17}
\end{array}$

notice, Papa Bear is 18inches in diameter, but radius is half that

and "edge per dollar" simply means, how much circumference per dollar
or $\bf \cfrac{Cmfc}{\$}$
