6200 miles per day = 258.3 miles/hour.
3.229 miles/hour
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
The benefit of using Google to determine average income rates is that Google will locate various websites that makes determining average income rates extremely easy.
The man would need to travel at an average speed of approximately 78 miles per hour to circumnavigate the Earth in 80 days. This calculation is based on the assumption that he travels continuously without delays or stops.
EDIT: To find the diameter, using the circumference - you divide the circumference by the value of Pi - Snakester1962 (Supervisor)
If you used a sextant and a marine chronometer you could determine your position and plot this on a map using latitude and longitude. If you did this regularly you would be able to plot your course.
Somewhere between four and five inches circumference. Measured around the middle of the penis (lengthwise) using a tape measure
Diameter = Circumference/pi
Diameter = circumference/pi
Do you mean, how do you determine the value of pi? Use a compass to draw a circle. Measure the measure the circumference of the circle using a string. Draw the diameter and measure it. The radius is ½ the diameter. pi = Circumference ÷ radius Do this several times and calculate the average. It should be close to 3.14 You could wrap a string around a can and to measure the circumference. Then measure the diameter of the top of the can by finding the longest distance across the top. One problem with this method is the top and bottom of the can is a bit larger than the middle. Circumference divided by diameter
Circumference of a circle = 2*pi*radius
Circumference = 2*pi*radius
