Arc length = angle (in rad!!) * radius:
45 degree = pi / 4 rad
Arc length = pi/ 4 * 15 = 15/4*pi feet or approx. 11.781 feet
Also in this case only, 45 degrees is 1/8 of the whole circle, so Arc length = 2pir/8 = pi/4*r, but only this case. the first formula always works!
Number 7: B=16. Number 8: A=30. Number 9: A=0
2^(1/2) is the same thing
Y = 1/6x^2 i would love the brainliest plz
