Question

what is the following formula used for 2x22/7xr

Answer 1

Answer:

Formula for circumference of a circle is (2 × 22/7 × r)

Step-by-step explanation:

Given (2 x 22/7 x r) formula can also be written as 2πr, as the value of π=22/7.

This formula is used to find out the circumference of a circle that is boundary of a circle.

Circumference of a circle (C) = 2πr

Here 'r' is radius of the circle.

Circumference of a circle is denoted by 'C'
