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

Answer:

The approximate circumference is 62.8 mm

Step-by-step 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
