Answer 1

Answer:

The ratio of the circumference of a circle to its diameter is the number π, a mathematical constant, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".

Since π is an irrational number so it cannot be expressed exactly as a fraction. Still, fractions such as 22/7 and other rational numbers are commonly(approximately) used for π.

So the circumference of a circle is given by π*d
