The formula for a cylinder's volume is
V = π r² h
V = 1345.6
π = 3.14
r = 5.8 cm
1345.6 = 3.14 * 5.8^2 h Multiply 3.14 and 5.8^2 together.
1345.6 = 105.6 h Divide by 105.6
1345.6 / 105.6 = h
h = 12.73 cm <<<< answer.
I don't see anything wrong with what I've done but I don't see the answer anywhere. Estimating 1345 can be rounded to 1300.
pi * 5.8^2 = 3 * 35 = 105 which we could round to 100.
1300 / 100 about = 13 So the answer should be in the region of 100.
I cannot see any reason to believe there is an error. If there is something that has not been copied correctly, I'd like to know what it is.
$2,940, because it’s 20% of $14,700
Answer:
B (6, 8)
C (1, 5)
see attached diagram (qu 1 is blue, qu2 is red)
Step-by-step explanation:
1.
A = (2, 3)
If B is 4 right and 5 up from point A, then
B = (2 + 4, 3 + 5) = (6, 8)
2. C = (9, 7)
If D is 8 left and 2 down from point C, then
C = (9 - 8, 7 - 2) = (1, 5)
You have, on the bottom the number of cars and on the left the corresponding probability.
The probability of having 4 cars is 0.05; the probability of having 5 cars is 0.05 again.
Therefore, the probability of having more than 3 cars is P(4) + P(5) = 0.10 which corresponds to 10%.
The correct answer is 0.10
