The volume for a triangular pyramid would be V=1/3AH, where A is the area or the triangular base,  and H would be the height. 
We need to find the area first. We can input the formula of the area of the triangular base, so it would be V=1/3(1/2bh)H. 
In this problem, H=8, b=6, and h=4. Plug that in to the formula. 
V=1/3(1/2*6*4)8. We can put that into a calculator, and get 32 cubic feet as our answer.

A cylinder has a volume of 375 cubic centimeters. The radius of the cylinder is 12.5 centimeters. What is the approximate height
mihalych1998 [28]

Answer:

0.8 would be the approximate height

Step-by-step explanation:

you can make an equation and solve for the height (x)

375 = 3.14(12.5^2)x

when you solve this equation, you specifically get 0.76. but your question is asking for the approximate, so you would round it up to 0.8. hope this helps!
