A rocket is launched from a cliff the relationship between the height of the rocket, H, in feet, and the time since lunch, t, in seconds, can be represented by the following function: h(t)= -16t^2 +80t+384 Help pls!!

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
