Answer:
C = 50.26 cm
Step-by-step explanation:
The question says that, "What is the measure of the circumference of a tube with a radius of 8 cm".
The circumference of a circle is given by :
C = 2πr
Put r = 8 cm in the above formula.
C = 2π × 8
C = 50.26 cm
So, the circumference of the circle is 50.26 cm.
