Height of the cylindrical pressure vessel = 9 feet
Diameter of the cylindrical pressure vessel = 6 feet
Then
Radius of the cylindrical pressure vessel = (6/2) feet
= 3 feet
Then
Volume of the cylindrical pressure vessel = <span>π<span>r^2</span></span><span>h</span>
= 3.14 * (3)^2 * 9 cubic feet
= 3.14 * 9 * 9 cubic feet
= 254.34 cubic feet
So the amount of gas that the cylindrical pressure vessel can hold is 254.34 cubic feet. I hope the procedure is clear enough for you to understand.
Answer: Hi!
Since this is a right triangle, we already know that one angle is 90 degrees. Since the angles of a triangle all add up to 180 degrees, and the two unknown angles will be equal, all we have to do is subtract 90 from 180 and then divide the difference by 2!
180 - 90 = 90
90 ÷ 2 = 45
The two missing angles are each 45 degrees.
(x = 45 and y = 45)
Make sure to put the degrees sign after your answers!
Hope this helps!
