WebTo calculate the segment of a circle, we consider the area of the segment which consists of a sector (arc + 2 radii) and a triangle. Hence, the formula for the area of a segment can be expressed as follows Area of a segment of circle = area of the sector - … WebA segment is the section between a chord and an arc. It is essentially a sector with the triangle cut out, so we need to use our knowledge of triangles here as well. To calculate … WebDec 15, 2024 · Use the formula C = πd to find the circumference if you know the diameter. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the … is that a adverb
