Answer 2

Answer:

Hence, value of circumference of the circle will be 44 cm

Step-by-step explanation:

In context to question asked,

We have to determine the circumference of circle.

As per data given in the question,

We have,

Diameter of circle = 14 cm

So, value of radius will be 14/2 = 7 cm

As we know that,

Circumference of circle is the length of outer border of the circle.

So, we have,

Formula for finding the circumference of circle as,

$Circumference \:C = 2 \Pi r , \\where \:'r' \:is \:the\: radius.$

So, for determining the value of circumference of circle we will put the value of radius in above formula.

Thus we will get.

$C = 2 \Pi r \\C = 2 \times \frac{22}{7} \times 7\\=>C = 2 \times 22 \\=>C = 44\:cm$
