Answer:
To find angle y you subtract the two angles form 180 degrees because it is a straight line. Then you subtract angle y and 72 from 180 because a triangle adds up to 180 degrees and you get angle x.

The circumference of a circle is 2PiR
We have 32Pi, so we can divide 32 by 2 to get the radius
The radius is 16.
The diameter is 2x the radius.
The diameter is 32.
Your answer is B.)
we know that
The area of a trapezoid is given by the formula
Area=h*(b1+b2)/2
where
<span>b1, b2 are the lengths of each base
h is the altitude (height)
</span>Remember that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular<span> distance between the two bases
</span> therefore
[area of trapezoid]=(11+5)*4/2--------> 64/2------> 32 cm²
the answer is 32 cm²
