Answer:
4 2/3
Step-by-step explanation:
42 in / 9in = 42 / 9 = 4 2/3
Trigonometric functions are not only used in cases of an object that has a cyclical behavior.
<h3>What is a trigonometric function?</h3>
It should be noted that trigonometric functions are real functions that relate the angle of a right angled triangle to the ratios of the two side lengths.
Trigonometric functions are not only used in cases of an object that has a cyclical behavior. It can be used to obtain unknown <em>angles</em> in geometric figures.
It can also be used to model the fluctuations in temperature data for a particular year.
The movement of a yo-yo can be modeled by a sinusoidal curve since it exhibits a periodic behavior.

The length of the similar tube will be 5041 cm.
<h3>What is the area?</h3>
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called the area of the circle.
Given that:-
- A piece of card, 1200 cm² in area, will make a tube 13 cm long. How long is a similar?
- Tube made from a similar piece of card with an area of 500square centimetres.
The radius of the first tube will be calculated as:-
1200 = 2πr ( 13 )
r = 12 / 2π x 113
r = 14.7 cm
Now the length of the second tube will be:-
500 = 2π x 14.7 x L
L = 500 / 2π x 14.7
L = 5.41 cm.
Therefore the length of a similar tube will be 5041 cm.
