Question

anonymous · Answer

If you are looking to calculate $$x^{y}$$ then look for something like ^.
If you are looking to calculate $$x*10^{y}$$ just look for EXP, E (note this is not the same as e), or *10^.

I'm still lost lol, let me tell you what I'm looking at......Circumference: The circumference of the clock was 42 inches. Find the diameter in inches.

anonymous · Answer

So you should know that the circumference of a circle is given by $$c=2*\pi*r$$and that the diameter is given by $$d=2*r$$so this gives $$c=d*\pi$$
Now you have c = 42 inches, so$$d=c/\pi=42 inches/\pi \approx 13.37inches$$

ok so how did you come up with 2?

C = pi x diameter, the diameter is twice the radius so the formula is usually presented as:

C = pi times 2r, or just squish it together to be:

C = 2pi r
