Answer:
The answer is 753.01 m².
Step-by-step explanation:
Given that the formula of sector is θ/360×π×r² where r represents radius of circle. Then, you have to substitute the values into the formula :

Let θ = 255°
Let π = 3.14,
Let r = 18.4m,


5/2 is the answer.
Have a nive day!
this is the answer hope it helps you
Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.
