What is the formula to find how far a wheel travels in one rotation? plz if you get the chance

it is also known as formula for circumfrence which is 2 times pi times radius. if radius was 5 then the circumfrence would be 10pi.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption
