Question

3. The ratio of the circumference of a circle to the diameter of the circle is.
(a) An integer
(b) A rational number
(c) An irrational number
(d) A whole number​

Answer 1

Answer:

an irrational numbser

Step-by-step explanation:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Answer 2

Answer :-

An irrational number

Explanation :-

• The circumference of a circle :o: is the perimeter of the circle.

Circumference = 2πr --- ➀

• The diameter of circle is represented as ‘d' and is the length of the longest chord that can be drawn within the circle.

Diameter = 2r --- ➁

• In this question, the ratio of circumference to the diameter is asked.

So dividing ➀ by ➁,

Circumference ÷ Diameter

= 2πr ÷ 2r

= π

which is an irrational number.
