Step-by-step explanation:
Answer:
cos(2sin−1x)=1−2x2
Step-by-step explanation:
et sin−1x=θ , so that, x=sinθ,|x|≤1,θ∈[−π2,π2].
Answer:
B
Step-by-step explanation:
120 degrees is 1/3 of the circumference of a circle.
So the formula is 2 * pi * r * theta / 360
Arc length = 2* 12 * 3.14 * 120/360
Arc length =25.12 feet
