Question

the distances around a circle Is its circumference true or false​

Answer 1

True. The distances around a circle Is its circumference

• circumference is defined as the perimeter of the circle.

• Circumference acts as an important quantity in not only finding the perimeter of circle but also in other features of circle like finding the length of secant, in determining area enclosed in circle, estimating the angle in radian for unit circle, etc.

• circumference of circle is always directly proportional to the radius of circle, ie when radius increases ,circumference also increases.

• The standard equation for finding circumference is given by, C = 2πr ,where π is a constant of proportionality and is a irrational number. π has the value of 3.14 (generally taken) and is mainly represented as 22/7.
