Answer:

radius of the pipe: 1.5 cm

Step-by-step explanation:

circumference formula of circle: 2πr

Here the radius is to be found and circumference is 9.42 cm

using the formula:

9.42 = 2πr

9.42 = 2(3.14)r [changing side changes multiplication to division]

r =
(9.42)/(2(3.14))

r =
(9.42)/(6.28)

r = 1.5

Therefore the radius of the pipe is 1.5 cm.
