i can only help you with the volume of #5.
So the volume of a cylinder is = πr²h.
First , put the numbers in the equation.
π(6)² (14)
Next you solve.
π(6)²(14) = 36 (14) π = 504π
V= 504π
Answer:
median then mean then range
3/10=15/50 and then 8/25=16/50
So, 3/10<8/25

since there are 4 books, and only one is a mathematics book, there is a 1/4 chance. in other words, 25%
