Answer:
213.52 cubic ft
Step-by-step explanation:
Diameter of pipe = 4ft
radius for circle is half of diameter
thus radius of pipe = 1/2 of 4ft = 2 ft
length of pipe = 17 feet
volume of cylinder is given by 
where r is the radius and l is the length of cylinder
.
thus volume of pipe is calculated below using above values

volume of pipe is 213.52 cubic ft.
The answer is C multiply and divide to left to right
Substituting m for 9
h(9) = 9^2 - 3*9
h(9) = 81 -27
h(9) = 54
Third option!
Let x be the number of pastries they must sell.
$3.50x≥140
This inequality states that for the number of pastries at 3.50 dollars each must be greater than or equal to 140. Solve for x.
You have to use sin, cos, tan and find the length of the last side and other angles. Then you have to put an imaginary line down the middle and use the sin, cos, tan to find the height and then do 1/2 base times height.
