Describe radius in math
WebArea of Rectangle. Area is the region covered by a two-dimensional shape in a plane. It is measured in square units. Therefore, the area of the rectangle is the area covered by its outer boundaries. It is equal to the product of length and width. The formula of area of rectangle is: A = L e n g t h × W i d t h u n i t 2. http://www.icoachmath.com/math_dictionary/Radius.html

WebRadius. more ... The distance from the center to the circumference of a circle. It is half of the circle's diameter. See: Diameter. Circle. WebIn two dimensions the answer is simply: as the radius increases, the area increases by the square of the increasing factor. That's a bit abstract, so let's give some examples. If the radius doubles, that's a factor of 2. The square of 2 is 4, so if the radius doubles the area is multiplied by 4. This is the example given in the video.
