Question

A circle with the diameter of 20 mm is showing what is the exact Sir conference obvious and then question to what is the approximate sir conference

Answer 1

The approximate circumference is 62.8 mm

Explanation:

Circumference is basically the perimeter of the circle

Circumference is given by

`2 *\pi *r`

Here the diameter is 20 mm, so the radius will be half of diameter = 10 mm

Substituting the given values, in above equation, we get -

Circumference =

`2 *3.14 * 10 \\62.8`mm

The approximate circumference is 62.8 mm
