Answer:
153.86 square feet
Step-by-step explanation:
The formula for the area of a circle is A=πr2
area = pi x radius squared
the radius is 7 feet, square that to get 49
multiply 49 by pi to get the area: 153.86 square feet
The probability would be 0.9993.
We find the z-score that corresponds with this situation. Z-scores are found using the formula:
Using our information we have:
Using a z-table (http://www.z-table.com), we look up the corresponding z-score for this. This gives us the area to the left of the score, so the heights that are less than 78 inches. This gives us the probability 0.9993.
Exact form: a= 32/81
Decimal form: a= 0.39506172...
