Question

Find the circumference of a circle whose radius is 28 cm

Answer 1

Given Radius=28 cm
we know that circumference of a circle=2pie r
2×22/7×28=176 cm

Answer 2

Answer:

Hence, the circumference of circle having radius 28 cm will be 176 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 = 28 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  $2 \times \Pi r = 2 \times \frac{22}{7} \times 28 = 2 \times 22 \times 4 = 176\:cm$
