Answer:
Approximately 55ft
Step-by-step explanation:
Answer:
step by step
Step-by-step explanation:
where
r = radius
h= height
Area of a cylinder = 2πrh+2πr^2
Area of a cylinder = 2π8(3)+2π8^2
Area of a cylinder = 176π = 552.92
Area of a hemisphere= 3r2π
Area of a hemisphere= 3(2)2π
Area of a hemisphere= 12π = 37.699111843
Area of the cylinder in this problem
176π - 12π = 164π
If you look at the attached graphic, you will see that the altitude (or height) of an equilateral triangle is:
Height = side length * sq root (3) / 2
Area = side^2 * sq root (3) / 4
Answer:
[see below]
Step-by-step explanation:
Volume of a triangular prism is: 
We are given the base of 5, the length of 12, and the height of 8. All measurements are in meters.

The volume of the prism should be 240 square meters.
