A sphere is a round-shaped object in three-dimensional space. All points on a sphere's surface are the same distance from its center point. Some examples of a sphere are a globe, marble, soccer ball and basketball.
Know MoreIn geometry, two important formulas relating to a sphere are how to find its volume and its surface area. Theses formulas are: volume = (4/3) × pi x r^3 and surfaces area = 4 x pi x r^2, where "r" refers to the radius and "pi" is approximated as 3.14.
A sphere is a geometrical object that is also perfectly symmetrical about its center. The distance from a sphere’s center to its surface is called the radius. A sphere does not have any vertices
Learn more about ShapesA sphere is a solid geometric figure defined as the set of all points equidistant from a common center point. It is perfectly symmetrical, and its surface is uniformly curved, without any edges, vertices or faces. It is the shape made when a semi-circle is rotated around its diameter.
Full Answer >A convex quadrilateral is a four-sided figure with interior angles of less than 180 degrees each and both of its diagonals contained within the shape. A diagonal is a line drawn from one angle to an opposite angle, and the two diagonals intersect at one point.
Full Answer >A shape that has seven sides is a heptagon. Heptagons can be either irregular or regular polygons. However, in a regular heptagon, all side lengths and interior angles are also equal. There also are 14 diagonals in this polygon.
Full Answer >A two-dimensional shape is a shape that has width and length but no depth. Another term for a two-dimensional shape is a plane shape, because a two-dimensional shape occurs on one plane, a flat surface that extends in every direction.
