Is this Geometry?

anonymous · Answer

Algebra 2, it's near the trigonometry section so it's almost there

condor34 · Answer

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

condor34 · Answer

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

condor34 · Answer

So it would be B.

condor34 · Answer

In the formula i put 3*pie*R i meant 2*pie*R sorry

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:
