Answer:
radius of the pipe: 1.5 cm
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 = [tex]\frac{9.42}{2(3.14)}[/tex]
r = [tex]\frac{9.42}{6.28}[/tex]
r = 1.5
Therefore the radius of the pipe is 1.5 cm.
