= 256 persons
p ( x ≥ 256 )
= 1 - ( 256/800 )
= 1 - 0.32
= 0.68
the probabiliy that more than 32% of those who carried out the survey would prefer ABC brand is 0.68.

Answer:
The answer is 1526.04
Step-by-step explanation:
First you do the formula and that is V= 3.14r^2h
V equals volume
r equals radius to the 2nd power and h equals hight 3.14 equals pie
So fill in the blanks
V=3.14 (9)^2(6)
V=3.14 (81) (6)
So 81 times 6 equals 486 then times 486 and 3.14 and that gets you 1526.04 and there is your answer
