Assuming you need the integral expressing the volume of

, the easiest setup is to integrate with respect to

first.
This is done with either


Thanks to symmetry, integrating with respect to either

or

first will be nearly identical.
First, with respect to

:


Next, with respec to

:

Answer:
24.85
multiply 3.5 to 7.1 then move the decimal to the left two times
Answer:
45??
Step-by-step explanation:
Answer:
25.38
Step-by-step explanation:
Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.
20^2+12^2=c^2
400+144=544=c^2
c=
then find corner of floor to opposite roof corner.
100+544=644=c^2
c=
so its about 25.38 feet
Answer:

Step-by-step explanation:
First, note that the angles shown are vertical angles. In other words, the two equations are equivalent to each other.
Therefore, set the equations equal to each other and solve for x;

Add 17 to both sides:

Subtract 6x from both sides:

Divide both sides by 2:

Therefore, the value of x is 12.
And we're done!
