Renewable Energy: The Energy Of The Future
Answer:
86.7%.
Explanation:
Considering the diagram, the path of the tip of the blades is a circle.
Hence, determine the circumference of the circle.
C = 2πr = 2π * 3 ft = 6π ft.
Then determine how long the blade edges are all together.
6 in * 5 blades = 30 inches
Therefore, to determine the fraction of the circumference of 30 inches, convert circumference to inches
6π ft * (12 in ÷ 1 ft) = 72π in.
Hence, the probability of Gerald’s randomly timed shot hitting a blade of the windmill
=> 30 ÷ 72π
=> 30 ÷ [72 * (22/7)]
= 13.3%.
Finally, the probability of his shot getting past the blades is then 100 – 13.3 = 86.7%.

The outcome of a poorly written subject line is that it won't be able to convey the message of what the writer would like to say to the reader or to the one that he or she had sent it to, It is because a subject line is the idea or tries to pertain and point out what is the message about. If it is written poorly, then it would only confuse the reader and in the same time there is no understanding and connection of the subject line to the message.
