Answer:
D.
Step-by-step explanation:
The traditional equation is 
the height - z multiplied by the area of the base, 
, or in this case, 2\pi(10+x)
Answer:
0.0214
Step-by-step explanation:
We can get these answer by finding the z-scores at first
Mathematically;
z-score = x-mean/sd
For 900;
z-score = 900-750/75 = 150/75 = 2
For 975
z-score = (975-750)/75 = 3
So the probability we want to calculate is;
P(2<x<3)
This can be calculated using the standard normal distribution table
From the standard score table;
P(2<x<3) = 0.0214
Four and seven hundredths
Fifteen and thirty eight hundredths
One hundred and sixty nine thousandths
Seven and two hundred and five thousandths
Nine and one tenth
Twelve and eighty six hundreths
