Answer: See below
Explanation:
Formula: V = pi x r^2 x h
Pi = 22/7
r = 15 ft
h = 35 ft
=> V = 22/7 x 35 x 15^2
=> V = 22 x 5 x 15^2
=> V = 110 x 225
=> V = 24,750 ft^2
Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.
Using the binomial distribution, we want all three to be defective.


#4 is 47, 48, 49
47+48+49=144
