WebHow did Greek scholars know the Earth was a sphere? They observed that ships disappeared over the horizon while their masts were still visible. They saw the curved shadow of the Earth on the Moon during lunar eclipses. And they noticed the changing positions of the stars in the sky.

WebJan 26, 2024 · CNN — While mapping radio waves across the universe, astronomers happened upon a celestial object releasing giant bursts of energy – and it’s unlike anything they’ve ever seen before. The... WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume. Created by Sal Khan and Monterey Institute for Technology and Education. Sort by: These properties are: The points on the sphere are all the same distance from a fixed point. Also, the ratio of the distance of its points... The contours and plane sections of the sphere are circles. This property defines the sphere uniquely. The sphere has constant width and constant girth. The ... See more A sphere (from Ancient Greek σφαῖρα (sphaîra) 'globe, ball') is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a … See more In analytic geometry, a sphere with center (x0, y0, z0) and radius r is the locus of all points (x, y, z) such that $${\displaystyle (x-x_{0})^{2}+(y-y_{0})^{2}+(z-z_{0})^{2}=r^{2}.}$$ Since it can be expressed as a quadratic polynomial, a sphere … See more Spherical geometry The basic elements of Euclidean plane geometry are points and lines. On the sphere, points are defined in the usual sense. The analogue … See more Ellipsoids An ellipsoid is a sphere that has been stretched or compressed in one or more directions.
