Answer: A circle’s perimeter is called the circumference. The symbol of the circumference is C. One can calculate by making use of the formula PZi x diameter, or 3.14 x d = C. Question 3: Explain what is the formula of semi-circle perimeter? Answer: The circle’s circumference formula, C, is C = 2 * pi * r.
Diameter formula can be easily derived by doubling the radius of the circle. Diameter can also be computed if we know the length of the circumference of the circle or area of the circle. Thus a unique circle will have a unique value of diameter. Source: en.wikipedia.org. Some Important Terms Related to a Circle. Centre: It is a point as a pivot ...

Answer: A Chord refers to a line segment that is joining any two points of the circle. The endpoints of these line segments lie on the circle’s circumference. Diameter refers to the chord that passes through the centre of the circle. In fact, it is also the longest chord possible in a circle. This term is taken from the Latin word “Chorda ...
