Answer:
cylinder:
curved sa = 2πrh
=> rectangle, breath = h, width = perimeter of circle = 2πr
total sa = 2πrh+2πr^2
=> curved sa + area of 2 circles
cone:
curved sa = πrl
=> treated as a triangle, base = circumference of circle, height = slant height
total sa = πr^2+πrl
=> curved sa + area of base (circle)
Solution:
we are given that
The federal budget for 2007 was 2.8 trillion dollars.
we have been asked to find
how much money did the government spend per second?
First we will find the number of seconds in one year
Number of seconds in 1 year
Seconds
Now we will dive the amount by the total number of seconds, we get
Hence the government is spending approximately 88787 dollars per second.

Answer:
A pentagon.
Step-by-step explanation:
A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.
108° ≥ 90°, so the angles are obtuse.
Therefore, a 2-D shape with 5 obtuse angles is a <u>pentagon</u>.
It is B. Because the 3$ doesn't have any variables and the 2 dollars is per hours so 2x
