Area of cone=3.14*9+3*6*3.14=27*3.14
=84.78 cm^2 if we cut into four identical pieces we get two triangle surfaces also for 1 piece and and 1/4 of the original surface area =21.195+15.588=36.783squarecm
1) B
This is because the x value = quarts and the y value = pints, there are 3 quarts and 6 pints.
2) A
Its going up 2 every time in the y axis, rise over run= 2 over 1
3) C
They are both at 0
Answer:
b.
821.9 cube meters
Step-by-step explanation:
Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?

b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?

Hence, a) 0.8413, b) 0.9987.
