What is the slant height x of the square pyramid? Enter your answer in the box, express your answer in radical form.
Nadya [2.5K]
<span> For this case we have a rectangle triangle where we know:
 hypotenuse of the triangle.
 Angle between the base of the triangle and the hypotenuse.
 We want to find the height of the triangle.
 For this, we use the following trigonometric relationship:
</span> sine (60) = x / 8&#10;
<span> From here, we clear the value of x.
 We have then:
</span> x = 8 * sine (60)&#10;&#10;x = 6.93 m<span>
 Answer:
 The inclined height of the pyramid is given by:
 x = 6.93 m</span>

A closed cylindrical tank contains 36pi cubic feet of water and is filled to half its capacity. When the tank is placed upright
pentagon [3]

Answer:

2.12 ft above ground level

Step-by-step explanation:

Volume of the cylindrical tank is 36*π

Tank is filled to half its capacity, that means tank is filled 18*π, and level of water is 4 feet, then the height of the cylinder is 8 feet

With the above information we can calculate the radius of the base of the cylinder, according to

V  =  36*π  = π*r²*h     ⇒  36 = r²*h     ⇒   36/8 = r²    ⇒  r = 2.12 ft

Then the radius of the base is  2.12 ft

When the cylindrical tank is place on its side, the level of water inside have to be 2.12 ft above ground level. That is the level of half its capacity
