Measurement and Geometry : Module 11 Year : PDF Version of module. The area of a plane figure is a measure of the amount of space inside it. Calculating areas is an important skill used by many people in their daily work. Builders and tradespeople often need to work out the areas and dimensions of the structures they are building, and so do architects, designers and engineers.

Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space. These are also referred to as the radius and center of the sphere, respectively. The longest straight line segment through the ball, connecting two points of the sphere, passes through the center and its length is thus twice the radius; it is a diameter of both the sphere and its ball. While outside mathematics the terms "sphere" and "ball" are sometimes used interchangeably, in mathematics the above distinction is made between a sphere , which is a two-dimensional closed surface embedded in a three-dimensional Euclidean space , and a ball , which is a three-dimensional shape that includes the sphere and everything inside the sphere a closed ball , or, more often, just the points inside , but not on the sphere an open ball. The distinction between ball and sphere has not always been maintained and especially older mathematical references talk about a sphere as a solid.
