What is approximately equal to 3.1415?

Well, this is the constant Pi. Pi is equal to the ratio of any circle's circumference to its diameter. In simpler terms: Take any sized circle (go on, draw one on paper) and measure how long a piece of string it takes to wrap it once around the circle. This is the circumference of the circle. Now measure the longest distance you can measure in the circle, so that would be from one side to the other side of the circle, over the middle bit, and that value is the diameter. Now take a calculator and divide the circumference by the diameter and voila, you should see a number equal to 3.1415 Go to wiki: http://en.wikipedia.org/wiki/Pi


What is the Amount of space a circle takes up?

The amount of space a circle takes up is determined by its area, which can be calculated using the formula A = π * r^2, where r is the radius of the circle.


A railroad curbe is laid out on a circle. What radius should be used if the track is to change direction by 20 degrees in a distance of 100 milesround your answer to the nearest mile?

The angle of direction change is equal to the angle of arc length on the circle. Thus the fraction of the arc length (the distance the change takes place in, 100 miles) divided by the total circumference of the circle is equal to the angle of the arclength divided by the total angle of the circle i.e. 20/360. Since the circumference is equal to 2*pi*radius the rest is a matter of simple algebra in order to find the radius.


What change takes place in the circumference of a circle if you reduce the radius to one third of its original length?

It reduces by one third.


Equator in nautical means?

A nautical mile takes into account the planet's circumference. You could view equator as a circle to establish distance.


Does displacement always equal distance traveled?

No, displacement and distance traveled are not always equal. Displacement is the shortest distance between the initial and final positions, whereas distance traveled takes into account the total path taken regardless of direction.


What is earths orbit circumferance?

The Earth's orbit circumference is approximately 940 million kilometers. It takes the Earth about 365.25 days to complete one orbit around the Sun.


When was Circle Takes the Square created?

Circle Takes the Square was created in 2000.


A string around the circumference of the earth is raised by one meter what length is?

same length + 6.28 meters the reason: the formula for circumference of a circle is 2pi*Radius Thus, if you want to raise by 1 meter you just add another 2pi meters. The amount it takes to raise 1 meter is independent of the initial circumference. 2*pi = 6.28


What are the difference of circumference formula and area formula?

Circumference is the distance around the object and Area is the amount of space it takes up.


How far do you travel for a one hour time change?

We travel about 1670.45 kms per hour relative to the space. Earth takes full circle in 24 hrs. So total distance covered in 24 hrs by any body present on the surface of the earth is equal to the circumference of the earth, which is 2*pi*r where "r" the radius of earth is 6378.1 kms.


What is the shape of path the earth takes?
