Question

The radius of a circle path is 10 cm. what length of a tape is required to wrap to once around the pipe?(pi= 3.14)

Answer 1

Length if tape required = 2 x pi x r
= 2 X 3.14 X 10
= 62.8 cm
### HOPE IT HELPS ###

Answer 2

$\sf\underline\bold{Solution}$

Radius of the pipe (r) = 10cm.

Length of tape required is equal to the circumference of the pipe = 2$\pi r$

= 2 × 3.14 × 10cm

= 62.8cm.

Therefore,

Length of the tape needed to wrap once around the pipe is 62.8cm.
