Answer:
-78
Step-by-step explanation:
3.606 is the answer
H^2 = P^2 + B^2
H^2 = 3^2 + 2^2
H^2 = 9+4
H^2 = 13
H = root 13
H = 3.606 (simple radical Form)
Step-by-step explanation:
a1 = -4 = -4/1, a2 = 8/3
r = a2/a1 = (8/3) / (-4/1) = -2/3
the formula :
an = a1. r^(n-1)
so,
an = (-4). (-2/3)^(n-1)
Moving to the edges it travels 2*3 + 2*2 = 10 units.
Then it moves in a circular path when it turns the 4 corners.
It goes through 90 degrees in each case - or pi/2 units
so 4 turns = 4 * pi/2 = 2 pi units
Answer is 10 + 2 pi.
