Question

find the circumference of a circle whose diameter is 35 cm

Answer 1

circumference =2pir
=2×(22/7)×17.5
=110 cm

Answer 2

Given, diameter = 35cm.
We know that, R = D/2...

So, radius of the circle is 17.5cm

We know that, circumference = 2πr...

substitute, the given values...

circumference = (2)(22/7)(17.5)

= (35)(22/7)
= (5)(22)
= 110cm..

Therefore, circumference of the circle fo given values is 110cm....
