Solve using trigonometry, find missing side

Step-by-step explanation:

1. sin 30 = x/16

   x= 16 sin 30

   x = 8

2. cos 60 = 22/x

   x = 22/cos 60

   x = 44

3. tan 45 = x/19

  x = 19 tan 45

   x= 19

4. tan 16 = x/13

   x = 13 tan 16

   x= 3.73

5. sin 54 = x/45

  x = 45 sin 54

  x= 36.41

6. sin 35 = z/23

 z =   23 sin 35

  z = 13.19

The formula for the Volume of a cylinder is
V=pi(d)(h)
So first, to find the diameter, you multiply the radius by 2, since the radius is half the diameter.
Next you plug in all the information you have.
V=pi(4)(20)
For the next step I used a calculator for pi and for precision on my calculations... then my answer was:
V=251.327412287...
So I rounded to the nearest tenth and got:
V=251.3
