Answer:

Step-by-step explanation:
This equation is more intimidating than the problem you have to solve.
You know that the sine of everything is always between -1 and +1. So for the entire expression to be >= 0, the a*tan(pi/8) bit has to be 1 at least. Given this, we can forget about the sin(...) term of the equation for the remainder of solving it.
You already figured out that tan(pi/8) is sqrt(2)-1.
So what we're saying is a * (sqrt(2) - 1) has to be 1 at least.
If we solve a(sqrt(2)-1) >= 1 for a we get:
a = 1/(sqrt(2)-1)
Divide by -8 on both sides
x=3
Answer:
LxWxH
Step-by-step explanation:
Volume can be calculated by using the formula: (length) x (width) x (height)
In this particular question, you are given the length as 13cm, the width as 8cm, and the height of 22cm.
To obtain the volume, you should plug these numbers into the formula (length) x (width) x (height)
When plugged in, the equation should look like this: (13cm) x (8cm) x (22cm).
When 13 x 8 x 22 =2288cm
Since you are calculating the volume, the answer will be given in centimeters cubed, so your final answer will be 2,288cm^3
