Answer:

= 868.1ft^3

Step-by-step explanation:

Volume of the square based pyramid = BH/3

B is the base area

H is the height of the pyramid

Base area = Length * Length

Base area = 14.1*14.1

BAse area = 198.81ft^2

Height = 13.1feet

Substitute

Volume = 198.81*13.1/3

Volume of the pyramid = 868.1ft^3

Hence the volume of a pyramid with the square base is 868.1ft^3

Answer:

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles

Step-by-step explanation:

We are given

Bethel Park is 28 miles directly west of Jeanette

10.3 miles directly south of Pittsburgh

We can draw diagram

we can see that this is triangle

so, we can use Pythagoras theorem

and we get

x^2=28^2+10.3^2

now, we can solve for x

x=\sqrt{28^2+10.3^2}

x=29.834miles

So,

The length of the road that runs straight from Pittsburgh to Jeanette is 29.8 miles
