So if we think of a test tube, it looks sort of like a cylinder. This means that its cross-section would be a circle. To find out how many turns a piece of thread would make around the test tube, we need to find the circumference of the test tube, then divide the length of the string by the circumference.
Step 1) Find the circumference
C = pi x diameter
C = 3.14 x 3
C = 9.42
Step 2) Divide the length of the string by the circumference
90.42 / 9.42 = 9.5987
The string would make approximately 9.60 turns around the test tube.
Hope this helps!! :)

Answer:
m∠NSR = 113°
m∠RSP = 67°
Step-by-step explanation:
Angle formed between the intersecting chords is one half the sum of the measures of the arcs intercepted by the angles.
m∠NSR = ![\frac{1}{2}[\text{arc}(NR)+\text{arc}(PQ)]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%5Ctext%7Barc%7D%28NR%29%2B%5Ctext%7Barc%7D%28PQ%29%5D)
= 
= 113°
Since, m∠NSR + m∠RSP = 180° [Linear pair of angles are supplementary]
113° + m∠RSP = 180°
m∠RSP = 180° - 113°
= 67°
