2 it is 2 I hope it is right
Answer:
8 3/4 cubic or 8.75
Step-by-step explanation:
To find volume it’s
Length * width * height
In degrees: 3π/4 radians = 135°
Angle of x=135° is in the 2nd Quadrant and has negative cos x values and positive sin x values.
cos 135° = cos ( 90° + 45°)= - sin 45° =

sin 135° = sin ( 90° + 45° ) = cos 45° =

. You can also see the graph in the attachment.
C= 3.14d
C= 3.14 x 9.06
C= 28.45
Deprecated means the price is decreased, so if something is deprecated by 50% (which just means 1/2 is taken away) its original price is just cut in half. so half of 1200 (1200 divided by 2) is 600. i think the answer is 600 :-)
