Answer:
≈ 5.36
Step-by-step explanation:
If we have a triangle in which the angle measure of it being broken down are the same, that means that the legs in which the angle measures are the same will have the same length.
If we already know that DE ≈ 9.28, then we can subtract this from 20 and divide by two to get BD, which is equal to EC.

However, I'm not 100% sure about this answer.
Hope this helped (and I hope I'm right)
Answer:
523.33 mm³
Step-by-step explanation:
The general formula for the volume of a sphere is:
V = 
The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:
V = 
V ≈ 523.33 mm³
Answer:
13 Adults and 6 Kids
Step-by-step explanation:
13*9 = $117
6*5.5 = $33
$117 + $33 = $150
