  • Radius=r=15ft
  • Height=h=120ft

\\ \tt\Rrightarrow V=\pi r^2h

\\ \tt\Rrightarrow V=\dfrac{22}{7}(15)^2(120)

\\ \tt\Rrightarrow V=\dfrac{22}{7}(225)(120)

\\ \tt\Rrightarrow V=42390ft^3

Answer:

  • 42390 ft³

Step-by-step explanation:

Since the tanks are congruent, they both have same volume.

If you rejoin them, it will form a cylinder with the radius of 15 ft and height of 120 ft.

<u>The volume of the cylinder:</u>

  • V = πr²h = 3.14*15²*120 = 84780 ft³

<u>The volume of each tank is half the volume of the cylinder:</u>

  • V(tank) = 84780 / 2 = 42390 ft³

Need help anyone who can help plz
olasank [31]

Answer:

A) x=40°

B) They have the same lengths.

Step-by-step explanation:

Since it is an isosceles triangle, both sides are the same. So if you add up all the angles of any triangle, it should always add up to 180°. There is a 50° angle and a right angle (90°) so you subtract 50 and 90 from 180 (180-50-90) and you get 40. X has to be 40° :)

A box is to be made from a rectangular piece of corrugated​ cardboard, where the length is 8 more inches than the​ width, by cut
Ksenya-84 [330]
The volume of a box like this is found by multiplying the length times the width times the height.  We are told that the length is 8 more inches than the width, so the width is w and the length is w + 8.  If we cut away 3 square inches from each corner, the height when we fold up those corners is going to be 3.  The volume is given as 27, so our formula looks like this:  27=(3)(w)(w+8).  When we do that multiplication, we have  27=3w^2+24w.  We need to solve for w so we can then solve for h.  Move the 27 over and set the quadratic equal to 0.  3w^2+24w-27=0.  We can then factor out a 3 to make the job easier:  3(w^2+8w-9)=0.  Now we can factor to solve for w.  The 2 numbers that add up to 8 and multiply to -9 are 9 and -1.  So (w+9) = 0, (w-1) = 0, or 3 = 0.  Of course 3 doesn't equal 0, so that's out.  w + 9 = 0 so w = -9.  w - 1 = 0 so w = 1.  There are 2 things in math that can never EVER be negative and those are time and distance/length.  So -9 is out.  That means that w = 1.  But don't forget that there was 6 inches cut off each side, so the width is 1 + 3 + 3 which is 7.  The length is w + 8 which means that the length is 7 + 8 or 15.  Those are the dimensions of the rectangle before it was cut.

The dimensions of a right triangle are shown in the diagram.
ryzh [129]

Answer:

18.4 cm

Step-by-step explanation:

For this problem, you would use <em>Pythagorean Theorem </em>or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. <u>Picture the 90 degree angle as an arrow pointing to the hypotenuse.</u>  In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!
