how many millimeters are present in 20.0 inches? 1 in = 2.54 cm
5100 mm
50.8 mm
508 mm
51 mm

Explanation:

Step1: Convert feet to meters for Mt. Kilimanjaro height

We know that $1\ m = 3.28084\ ft$. Let $h$ be the height in meters. Then $h=\frac{19565}{3.28084}\ m$.

Step2: Convert meters to kilometers

Since $1\ km = 1000\ m$, the height in kilometers $H=\frac{19565}{3.28084\times1000}\ km$.
$H=\frac{19565}{3280.84}\approx 5.963412\ km$.

Step3: Convert inches to centimeters for the second - question

Given $1\ in=2.54\ cm$, for 20.0 inches, the length in centimeters $l = 20.0\times2.54\ cm$.
$l = 50.8\ cm$.

Step4: Convert centimeters to millimeters

Since $1\ cm = 10\ mm$, the length in millimeters $L=50.8\times10\ mm = 508\ mm$.

Answer:

Question 1: 5.963412 km
Question 2: 508 mm
