Question

the radius of circle is 7 cm. find the circumference of circle

Answer 1

The formula used for finding the circumference is 2πr
So
2×22/7×7
=2×22
=44 cm
Hence 44 cm is the circumference of the circle

Answer 2

Answer:

Hence, the circumference of circle having radius 7 cm will be 44 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 = 7 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  $2 \times \Pi r = 2 \times \frac{22}{7} \times 7 = 2 \times 22 = 44\:cm$
