Answer:

Step-by-step explanation:
The volume of a cylinder,
is given by the formula,

Where,
is the radius and
is the height of the cylinder.
Here,
,
. Plug in these values and solve for radius,
.
This gives,

Taking square root both sides, we get

Therefore, the radius of the cylinder can be expressed as
.
<h3>
Answer: 20.3</h3>
Work Shown:
tan(angle) = opposite/adjacent
tan(B) = AC/AB
tan(67) = x/8.6
8.6*tan(67) = x
x = 8.6*tan(67)
x = 20.2603303460843 ... make sure your calculator is in degree mode
x = 20.3 .... rounding to 3 significant figures
