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 … WebThe diameter of a metallic sphere is 6 cm. The sphere is melted and drawn into a wire of uniform circular cross-section. If the length of the wire is 3 6 m, find the radius of its cross-section. Medium. View solution > The diameter of a copper sphere is 6 cm. best food delivery near me now As mentioned earlier r is the sphere's radius; any line from the center to a point on the sphere is also called a radius. If a radius is extended through the center to the opposite side of the sphere, it creates a diameter. Like the radius, the length of a diameter is also called the diameter, and denoted d. Diameters … 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 Enclosed volume In three dimensions, the volume inside a sphere (that is, the volume of a ball, but classically referred to as the volume of a sphere) is where r is the … See more Circles Circles on the sphere are, like circles in the plane, made up of all points a certain distance from a fixed point on the sphere. The intersection of … See more The geometry of the sphere was studied by the Greeks. Euclid's Elements defines the sphere in book XI, discusses various properties of the sphere in book XII, and shows how to inscribe the five regular polyhedra within a sphere in book XIII. Euclid does not … 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 … 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 of the "line" is the geodesic, which is a great circle; the defining … See more Ellipsoids An ellipsoid is a sphere that has been stretched or compressed in one or more directions. More exactly, it is the image of a sphere under an affine transformation. An ellipsoid bears the same relationship to the sphere that an See more WebIf the diameter of the sphere = 2r, then the surface area of the sphere = 4πr 2 square units. The area of a sphere is always expressed in square units, like m 2, in 2, cm 2, yd 2, etc. The volume of a sphere is the total amount of capacity immersed in a sphere that can be calculated using the volume formula for the sphere which is V = (4/3)πr ... 3 year old birthday party themes boy WebThe formula to calculate the diameter of a sphere is 2 r. d = 2r. Circumference: The circumference of a sphere can be defined as the greatest cross-section of a circle that we can cut from a sphere. The formula for the circumference of a sphere is given by 2 × π × r. C = 2 π r, where r is the radius of the circle and π (pi) is ... WebA sphere is a solid bounded by a surface all points of which are equally distant a point within, called center. A radius is the distance between the center and the surface. A diameter of a sphere is a straight line drawn … 3 year old birthday party ideas boy near me WebThere are 4 main formulas for a sphere. 1. Diameter of the Sphere.
