Sphere Vs Circle Math
The circle exists in two dimension and in a plane.
Sphere vs circle math. Both areas are relative to r squared and grow at the same rate. Circle as a two dimensional figure has only an area πr 2. A circle is a 2d figure whereas a sphere is a 3d object having volume. Sphere on the other hand as a three dimensional figure object has an area 4πr 2 and a volume 4 3πr 3.
You can compare the two as a drawing of a tennis ball on a piece of paper and the ball itself in real life. One can only calculate the surface area of a circle whereas it is possible to calculate the volume of a sphere. A circle is a two dimensional figure while a sphere is a three dimensional figure. Two points on a sphere that are not antipodal define a unique great circle it traces the shortest path between the two points.
A circle is a round plane figure whose boundary the circumference consists of points equidistant from a fixed point the centre. It said that the surface area of a sphere red grows more slowly than the area of the biggest circle inside the area green. Lines of longitude and the equator of the earth are examples of great circles. Somehow this was supposed to make me understand curved spacetime and gravity.
But wtf man it doesn t make sense.
