Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9
The answer would be if you were solving for y. Y= 1/2x+3/8
-44.09 i dont understand why we must have 20 characters but OK
Total weight of the 8 backpacks = 8 x 14 = 112 pounds
Total weight of the 12 backpacks = 12 x 9 = 108 pounds
Total weight of all the 20 backpacks = 220 pounds
Mean weight of the 20 backpacks = 220 ÷ 20 = 11 pounds
----------------------------------------------------------------------------------------
Answer: The mean weight of the 20 backpacks is 11 pounds

Answer:
Step-by-step explanation:
we know that
The diameter divide a circle into two equal parts
so
The measure of arc FAC is equal to 180 degrees (Remember that a complete circle subtends a central angle of 360 degrees)
we have that
---> given problem
----> by central angle
----> given problem
so
therefore
----> by angle addition postulate
substitute
