WebIn economics, circularitymeans a product, service, or resource is renewed or regenerated, rather than wasted. In a circular economy, when a product or resource is used, it's then recycled, composted, or re-used in a way that … Roundness is the measure of how closely the shape of an object approaches that of a mathematically perfect circle. Roundness applies in two dimensions, such as the cross sectional circles along a cylindrical object such as a shaft or a cylindrical roller for a bearing. In geometric dimensioning and tolerancing, control of a cylinder can also include its fidelity to the longitudinal axis, yielding cylindricity. The analogue of roundness in three dimensions (that is, for spheres) is s…
