Uhm ok
the answer is 5 although u probably don’t need that
<span>Answer:
17576=pir^2h
the amount of material M=2pir^2 +2pirh
M=2pir^2+2pir(17576/pir^2)
DrM= 4pir- 35152/r^2
DrM=0
0=4pir- 35152/r^2
r=(13*2^(2/3))/pi^(1/3)
17576=pi((13*2^(2/3))/pi^(1/3))^2)h
17576/(pi((13*2^(2/3))/pi^(1/3))^2))=h
r=14.0901
h=28.1801
M=3742.21 cm^2</span>
Sylvia is correct because a right triangle needs to have 1 right angle and 2 acute angles, it cannot have more than 1 right angle.
C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X
