Answer:

Hence, the circumference of circle having radius 21 cm will be 132 cm

Step-by-step explanation:

In context to question asked,

We have to determine the circumference of the circle.

From the data given in the question,

We have,

Radius of circle = 21 cm

As we know that,

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

As we know that,

We have,

formula for finding circumference of circle is 2\times \Pi r

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

Thus we will get,

Circumference of circle  2 \times \Pi r = 2 \times \frac{22}{7} \times 21 = 2 \times 22 \times 3 = 132\:cm
