This is supposed to be an easy problem but I cant figure out why the answer is not :
pi /3 - ( 1/2 + √3/2 )
Help me plz
The selected answer is right.
The curved part is 1/6 of the whole circle. The whole circle has a circumferene of 2π, so the curved length is π/3.
Trigonometry is used to show that the shorter straight side has length 1/2 and the longer straight side has length √3/2.
Why did the vector cross the road?
It wanted to be normal.
