Question

The outer diameter of a pipe is 100 cm, and the outer circumferences will be

Answer 1

Answer:

314 cm

Step-by-step explanation:

Given outer diameter of pipe is 100 cm.

We have to find outer circumference of pipe.

We know that diameter = 2 radius

So radius = 100 / 2 cm

               = 50 cm

We know that  circumference = 2 π r

putting values here

Circumference = 2 × 3.14 × 50 cm

                        = 3.14 × 100 cm

                        = 314 cm

Thus we get  outer circumferences of pipe is 314 cm
