How To Use The Arc Length Calculator
First, press [prgm], then scroll to the “ARCLEN” or whatever you named the program. And then press [enter] and then [enter] again. Then the program will take you to the screen below.
From here you will select weather you would like to run the program in degree or radian mode. To select an option, just press [enter]. Then you should arrive at the screen below.
From here you can choose to find the arc length, angle measure, or radius of a circle or section of a circle, Or you can quit the program. Once again select what you would like to solve for by pressing [enter]. As an example I will choose to find arc length.
Then the calculator will prompt you to enter the needed information to find whatever you are looking for. In my case I will enter the radius and the angle measure to find the arc length. Once you have entered the values, press [enter] again and the program will give you the answer.
As you can see at the bottom of the image it says “ENTER TO RUN AGAIN”. If you press [enter], the program will take you back to the main menu
Here you can easily solve another problem involving arc length. Note that the program will stay in whatever mode (degrees or radians) you put it in in the begging. If you would like to change that, you will have to select option 4 to quit the program and start from the beginning.
