Sorry if im wrong but i am pretty sure that is 266
Answer:
4.19
Step-by-step explanation:
just use the formula 2pir^2
I think b sorry if it’s wrong :(
It hits the ground at h=0
0=-16t^2-16t+96
undistribute -16
0=-16(t^2+t-6)
factor
0=-16(t-2)(t+3)
set to zero
0=t-2
2=t
t+3=0
t=-3, nope, we can't have negative time
at t=2, or 2 seconds
