Scoring a hole-in-one is the greatest shot a golfer can make. once 5 professional golfers each made holes-in-one on the 7th hole at the same golf course at the same tournament. it has been found that the estimated probability of making a hole-in-one is (1/2494) for male professionals. suppose that a sample of 5 professional male golfers is randomly selected.
(a) what is the probability that at least one of these golfers makes a hole-in-one on the 10th hole at the same tournament?
(b) what is the probability that all of these golfers make a hole-in-one on the 10th hole at the same tournament?

A) Probability  that at least one of these golfers makes a hole in one on the 10th hole at the same tournament is 

=1−(2493/2494)^5
=1-(0.99)^5
= 1- 0.96
=0.4

b) The probability that all of these golfers make a hole-in-one on the 10th hole at the same tournament
=(1/2494)5

which is nearly zero.

The formula for cylinder of pi is v = π r ^ 2 h.

So you are going to do pi x 6^2 x 12 = 1357.168026350791 then divide 1357.168026350791 by pi and you get C. 432 pi in.^2

Also here is a link to a calculator that can really help with problems like this.
