Question

Find the circumference of the circle. Give the exact circumference and then anapproximation

Answer 1

Given:

A circle with diameter 11 cm.

Required:

Find the circumference of the circle.

Step-by-step explanation:

We know circumference formula of circle

`C=2\pi r\text{ OR }C=\pi d`

We have diameter equal 11 cm

So,

`\begin{gathered} C=3.14*11 \\ C=34.54cm \end{gathered}`

Answer:

Hence, exact value is 34.54 cm and approximation can be written as 34.5 cm
