The formula to calculate is: πD (or 2πr) On calculator, π=3.141592654 So it would be 12.56637062cm
the formula used to calculate a slope is: m=y2-y1/x2-x1
The formula to figure out the circumference of a circle is C=2(pi)r. So with a circle that has a radius of 40 inches, you can set up the formula like: C=2(pi)40. To figure this out on a calculator, multiply 2 with pi and then multiply that answer with 40. If you do not have a pi symbol on your calculator you can multiply 2 with 3.14159 then multiply that answer with 40.
x2/144 - y2/25 = 1
you get a calculator and learn the correct formula
It depends on your calculator. You may find that you need to go to set up and then display mode.
