In order to complete this question we would need to know the height of the drum and the diameter. then plug the information into this formula. A=2πrh+2πr2 (r= 1/2 diameter)

If you need to show your work look at the picture
A=g
v=⌠g dt
v=gt+C, where C=v initial
v=gt+vi
h=⌠v dt
h=gt^2/2+vit+C, where C=h initial
h=gt^2/2+vit+hi
We are told that vi=42 ft/s, hi=0, and we know g≈-32 ft/s^2 so
h(t)=-16t^2+42t
The ball will hit the ground when h=0 so
-16t^2+42t=0
-2t(8t-21)=0, since t>0
8t-21=0
8t=21
t=21/8
t=2.625 sec
t≈2.6 sec (to nearest tenth of a second)
For the answer to the question above asking What is the measure of each angle formed if A 54-degree angle is bisected by a ray?
well bisect means to divide by 2
<span>so obviously if 54 is bisected it gives </span>
<span>54/2=27
</span>i hope this helps
