Question about Texas Instruments TI-30X-IISTK Scientific Calculator

1 Answer

TI-30x IIS stopped working

This cheap but good pocket calculator stopped working suddenly. I suspected the battery was the problem and took the old one out. Never tested the battery and now don't remember which way it was in the calculator. The battery is a size of a dime and there is red wires on one electode and black wires to its face with many spots that will touch the battery. Now I tried both ways and it still doesn't come on and now think I might have shorted it out. It says to reset you need to press "on" & "clear". Now I think that I need to press both at the same time which I still have not tried. I have rather press "on" first and then "clear". Have I broke it or should go back to battery store see if they can get it to work? The battery that goes with it is CR2025 3V.

After about 4 times putting the battery in it, it finally started working. I was just about ready to return back to the battery store.

Is there an inexpensive manual avail for TDC Vivid Mainliner 300 slide proj.?


I see manuals on eBay for around $14 but nothing cheap or free. It's unfortunately one of those that is just rare enough that nobody wants to cut anything lose. Sorry... You might try a Google search if you are having a specific problem - sometimes you can find a support or community forum that has a thread about the issue.

Good luck

What is the Formula for calculating volume of a cylinder


volume is calculated by finding the area multiplied by the length or height . That is Pi X radius squared X length
example --tube 6"dia 12"long what is the volume?
Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"
If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

The circumference of a circle is 47.1 feet. What is the diameter of the circle?


The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1
------ = d
pi

I get 14.99' or approximately 15' as the diameter.

Good luck,
Paul
