Why are the equator and all lines of longitude called great circles?
The equator and all lines of longitude are called great circles because the represent the circumference of the earth. The other latitude lines along the globe are smaller then the actually circumference.
Why the lines of latitudes decrease in size towards the poles?
Lines of latitude, or parallels, are imaginary circles that run parallel to the equator. As you move from the equator towards the poles, these circles decrease in circumference due to the Earth's spherical shape. At the equator, the latitude is 0 degrees and the circumference is largest, while at the poles, the lines converge to a single point at 90 degrees north and south, resulting in their diminishing size. This geometric property is a direct consequence of the Earth's curvature.
What is the answer to circles and circumference?
circumference = 2*pi*radius or pi*diameter
What is a portion of a circles circumference?
It is an arc
A fraction of a circles circumference?
An arc
What is the converse of If two circles have the same diameter then they have the same circumference?
The converse of the statement "If two circles have the same diameter, then they have the same circumference" is "If two circles have the same circumference, then they have the same diameter." This means that if you know two circles share identical circumferences, you can conclude that their diameters are also equal.
How do you find the circumference of circles?
The circumference of a circle = pi*diametre = 2pi*radius
How is pi used to find circumference of circles?
Pi times the diameter of a circle gives its circumference.
What is the ratio to any circles circumference to the diameter?
The ratio of the circumference of a circle to its diameter is Pi. (3.14159)
If Two different circles have same circumference?
Then they are similar.
Which planet has the largest circumference?
The planet with the largest circumference is Jupiter. About its equator, the circumference measure about 449,197 kilometers. Jupiter is an outer planet that also is the largest in the solar system.
If all your blood vessels were laid end to end could they make two circles around the moon?
The equator, around Earth's total circumference as a sphere.
