Answer:
The answer is "778"
Step-by-step explanation:
Given value:
![\to \mu= 711\\\\\to \sigma= 80\\\\\to P(Z >0.84) = 0.20\\\\\to z = 0.84](https://tex.z-dn.net/?f=%5Cto%20%5Cmu%3D%20711%5C%5C%5C%5C%5Cto%20%5Csigma%3D%2080%5C%5C%5C%5C%5Cto%20P%28Z%20%3E0.84%29%20%3D%200.20%5C%5C%5C%5C%5Cto%20z%20%3D%200.84)
The formula for z-score:
The area of the track will be 78501 m². The area of the track is equal to the area of the circle.
<h3>What is the area?</h3>
The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.
The area of the track is found as;
![\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2](https://tex.z-dn.net/?f=%5Crm%20A%3D%5Cfrac%7B%5Cpi%7D%7B4%7D%20d%5E2%20%5C%5C%5C%5C%20%5Crm%20A%3D%5Cfrac%7B3.14%7D%7B4%7D%20%28100%29%5E2%20%5C%5C%5C%5C%20A%3D7850%20%5C%20m%5E2)
Hence, the area of the track will be 78501 m².
