  • your wrong! well your right but there is an easier way.

    just use: A=1/2 x r^2 x theta. where theta is in radians.

  • I know that, but in my regular geometry class we stick to degrees.

  • you forget to put 47.12 cm² :D

  • This is so easy!! I solved it before the video was even done. And btw the decimal answer is 47.1 not 47.12!!

  • video would be so much better without the music lol

  • I can't hear you.

  • I agree..that damn music takes away from the learning .... I am forcing to hear what the man is say

  • what's the formula???

  • yes

  • Shouldn't that be cm squared since it is talking about area?
