Question

The radius of a circular pipe is 10 cm . What length of a tape is required to wrap once around the pipe?

Answer 1

Given-Radius of circle =10cm
length of tape=circumference of circle
so, circumference of circle =2πr
2*3.14*r
2*3.14*10
2*31.4
=62.8cm
therefore, length of tape required to wrap around a circular pipe of radius 10cm is 62.8cm..

Answer 2

And:- radius of circle = circumference of circle so, circumference of circle = 2πr

= 2*3.14*10

= 2* 31.4

=62.8 cm = Answer
