Question

find the circumference of circle if the diameter of circle is 14.​

Answer 1

The given data;

diameter of circle is 14

find out;

circumference of circle ;

let us ;

diameter = 14cm

radius r =  14/2

​  =7cm

circumference=2πr

=2×  22/7×7

=44cm

Hence the  circumference of circle is =44cm

Answer 2

Given: Diameter = 14 units

So, the radius will be 7 units ( as radius is half od the diameter)

We have to find the circumference of the circle.

So for determining the circumference we will use the formula

Circumference = 2πr

Putting the value of radius in the formula,

Circumference = 2× $\frac{22}{7}$ × 7

                         = 44 units.

The circumference of the circle will be 44 units.
