x = 9
Given:
The radius of inner circle = 13 yd.
The width of the shaded region = 8 yd
To find the area of the shaded region.
Now,
The radius of the outer circle = 13+8 yd = 21 yd
Formula
The area of a circle of radius r unit is 
sq unit.
where, 
= The area of the shaded region
= Area of the outer region
= Area of the inner region
Now,
sq yd
And,
sq yd
Therefore,
sq yd
sq yd
Hence,
The area of the shaded region 854.08 sq yd.
Answer:
968π ≈ 3041 . . . cubic units
Step-by-step explanation:
The usual formula for the volume of a cylinder is ...
V = πr²h
For your given dimensions, the volume is found by putting the values into the formula and doing the arithmetic.
V = π(11²)(8) = 968π . . . . cubic units
V ≈ 3041 cubic units

Answer:
x = 13
Step-by-step explanation:
The tirangle ABC is given as equilateral. Every angle is therefore =. Not only that, each angle is 60 degrees.
If you need proof of that, remember that x + x + x = 180. Every triangle has 180 degrees.
if 3x = 180 then 1 x is 60
8x - 44 = 60 Add 44 to both sides.
8x = 60 + 44
8x = 104 Divide by 8
x = 104/8
x = 13
