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.

Answer:
26
Step-by-step explanation:
We know that the entire angle measures 66 degrees.
Therefore, angle y plus 40 degrees must equal 66.
In an equation:
To solve for y, subtract 40 from both sides:
So, the measure of angle y is 26 degrees.
And we're done!
12 - all divisible by it (2*12=24, 3*12=36, 12*5=60)
