Answer:
Part 1) The volume of each beam is 
Part 2) You can fill 
Part 3) Yes, the amount of sand left over is 
Step-by-step explanation:
Part 1) What is the total volume of each beam?
The volume of a cylinder is equal to

we have

----> the radius is half the diameter
assume

substitute the values


Part 2) How many beams can you fill with this sand?
we know that
You are given a container with a 50,000 sq ft of sand for your beams
<em>Note</em> Is a 50,000 cubic foot of sand instead of 50,000 sq ft of sand
Divide the total volume of sand by the volume of each beam to obtain the number of beams

Round down

Part 3) Will you have any sand left over? If so how much?
yes

Two ways:
Step-by-step explanation:
1. First way. Using the trig unit circle.
tan (pi - x) = - tan x
2. Second way. Apply the identity:
tan(a-b)=tan a- tan b/ 1 - tan a×tan b
tan (π - x)= tan π - tanx/1 - tan(π)×tanx
Since tan (pi) = 0, therefor:
tan(π−x)=−tanx
What’s the question though?
Answer:
its to blurry
Step-by-step explanation:
70% equals to 70/100 in fraction form.
But, you need to write it in simplest form. so, divide both of them from 10 'cause they both can divide completely by it.
70/100 = 7/10
so, your answer is 7/10
