Sarah the cheetah ran the 100 meters in 5.9523s. Subtract 5.9523 from 9.6
Since we know a circle has 360 degrees, the sector bounded by a 90 degree arc will be a quarter of circle (360/90 = 4). Then, to calculate the area of that sector, we can calculate the total area of the circle of radius 10, and then divide it by 4.
The area of a cirlce of radius r is:

Then, the area of the sector would be:


The answer is that 48 have been planted with bean and corn and 24 acres is beans and another 24 acres is corn

Given:

Desired Outcome:
Probability that it will last 10 years
z-score for the sample:

p-value
For the z-score of 1.9376, the p-value is 0.9738 or 97.38%
Hence, the probability that it will last longer than 10 years if you randonly purchase one item is 97.38%
