Question

The radius of a circular path is 10 cm.what length of a tape require to wrap around the pipe?

Answer 1

r=10cm
perimeter=2 *3.14*10
               =2*31.4
               =62.8 
               

Answer 2

Solution :-

Radius of the pipe = 10 cm

Circumference of the pipe = 2πr

⇒ 2*22/7*10

⇒ 440/7

= 62.857 cm 

So, the length of the tape is 62.857 cm to wrap around the pipe.
