Question

The radius of circular pipe is 12cm,what length of tape is required to wrap once around the pipe(use pie =3.14)​

Answer 1

Answer:

75.36 cm

Step-by-step explanation:

We need to find the circumference of the pipe.

Circumference of a circle = 2$\pi$r   (where r is the radius)

Given:

• r = 12 cm
• $\pi$ = 3.14

⇒ circumference = 2 x 3.14 x 12 = 75.36 cm
