Heather dropped a water balloon over the side of a building from a height of 80 feet. The approximate height of the balloon at any point during its fall can be represented by the following quadratic equation. h= -16squared plus 80. About how long did it take for the balloon to hit the ground?

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

answer:   2 multiplied by x =24
