Answer:
251.2 units³ ; 80π units³
Step-by-step explanation:
Volume of a Cylinder is: 
'r' is the radius.
'h' is he height.
The cylinder has a base radius of 4 units and the height 5 units.
<h3>Using 3.14 for Pi:</h3>

The approximate volume is 251.2 units³.
<h3>In terms of pi:</h3>

The exact volume is 80π units³.
So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.
now, if we take 28 to be the 100%, what is 21 off of it in percentage?
Answer:
75 degrees
Step-by-step explanation:
those two angles = 180
180-105 =75
