Question

How to find the circumference of a circle that is 42m and has diameter

Answer 1

Answer:

Circumference of the circle is $131.88m$

Step-by-step explanation:

we have to find the circumference of the given circle.

Given:

                     Diameter=42 m

          $\\diameter=2*radius\\42 =2*radius\\radius=42/2\\radius=21 m$

Circumference of a circle= $2\pi r$

                          $=2*\pi *21\\=2*3.14*21\\=42*3.14\\=131.88$

So, the circumference of the circle is $131.88m$
