Question

the radius of a circular pipe is 5cm What length of tape is required to wrap twice around the pipe

Answer 1

Answer:20cm.

Step-by-step explanation:

Diameter required to wrap one time= 5×2=10cm.

Two times= 10×2=20cm.

Answer 2

Answer:

use the circumference formula

Step-by-step explanation:

circumference = 2$\pi$r

2(circumference) = 4$/pi$r

2(circumference) = 4 x 22/7 x 5

2(circumference) = 440/7

length of tape to wrap twice around the pipe = 62.85714 <approx>
