Volume of a cylinder = PI x r^2 x H
r = 4 so r^2 = 4^2 = 16
h = 3
Volume = 3.14 x 16 x 3 = 150.72 ft^3
it doesn't say how to round the answer so you may need to round it
they are Acute angles because is is smaller than 90 degrees
obtuse = >90 degrees
right angle = 90 degrees
Acute = < 90 degrees
I hope this helps:)
You can pull a common factor from both terms:

Next, pull a factor of 4 from 24, and 25 from the power of 5; since 100 = 25*4, we have
