A pyramid shaped building is 836 ft tall with a square base that is 156 ft on each side. What is the volume of the pyramid?

pishuonlain [190]

Answer:

6781632 ft ^ 3

Step-by-step explanation:

The first thing is to know the formula for the volume of a pyramid:

V = 1/3 * Ab * h

That is, it is one third of the product between the area of the base and the height.

The base area would be:

Ab = l ^ 2

the side equals 156 ft, replacing:

Ab = 156 ^ 2

Ab = 24336 ft ^ 2

now, replacing in the volume formula:

V = 1/3 * 24336 * 836

V = 6781632

Which means that the volume of the pyramid is 6781632 ft ^ 3

Solve the following proportion for 17/13=9/u

ValentinkaMS [17]

Answer:

Solution,

$\frac{17}{13} = \frac{9}{u}$

Sinplify the equation using cross multiplication

$17 \times u = 13 \times 9$

Calculate the product

$17u = 117$

Divide both sides of the equation by 17

$\frac{17u}{17} = \frac{117}{17}$

Calculate

$u = 6.88$

Hope this helps...

Good luck on your assignment..
