    The formula u want to use is arc length= central angle/360 *3Pie R

    so it would look like this: 40/360*2*pie*7=4.886921905584123

    I took one lucky guess lol xD it just made sense to be less than 280 but more than 0.70. I just wanted to actually have the work shown to me c: thank you Condor, you'll receive a medal and a fan c:
