WebApr 13, 2024 · A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r r (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices. A sphere with radius r r has a volume of \frac {4} {3} \pi r^3 34πr3 and a surface area of 4 \pi r^2 4πr2. WebMaps that preserve area On an equal-area projection, the size of any area on the map is in true proportion to its size on the earth. You should use equal-area projections to show: · The density of an attribute with dots (for example, population density) · The spatial extent of a categorical attribute (for example, land use maps) arahan membawa kenderaan

WebFor the equal area projection, the following mapping is used to convert the Cartesian coordinates of a point on the unit sphere to the corresponding point on the cylinder wrapped around it: . WebThe area of a rectangle is length x width. In this case, length = the height of the cylinder and width = the circumference of the end of the cylinder (the circle). The length is given, and the width can be calculated using the formula for circumference of a circle. WebSo-called equal-area projections maintain correct proportions in the sizes of areas on the globe and corresponding areas on the projected grid (allowing for differences in scale, of course). Notice that the shapes of the ellipses in the Cylindrical Equal Area projection above are distorted, but the areas each one occupies are equivalent. arahan menjalankan tugas kewangan
