Answer:
Downtown Dubai is the city’s busy tourism hub, home to the towering Burj Khalifa skyscraper, with its observation deck, and the dancing Dubai Fountain, where crowds gather to watch music and light shows. The sprawling Dubai Mall offers global fashion brands and casual eateries, while Emaar Boulevard.
Here the absolute uncertainty is not given, so assume the last reported digit can vary by 1. That means the absolute uncertainty is 0.1 × 10^4 cm.
Now, when you perform math operations on the measurements, you have to adjust the absolute uncertainty of the final result. In particular:
1. If you multiply the measurement by some number "n" (which has zero uncertainty), then you must also multiply the uncertainty by "n".
2. If you square the measurement, then you must multiply the uncertainty by 2M (where "M" is the amount of the measurement)
3. And lastly, if you cube the measurement, you must multiply the uncertainty by 3M²So, if the measured radius is "R" (1.8x10^4 cm); and the uncertainty is "Δ" (0.1 × 10^4 cm), then the area is:
Area = πR² +/- π(2R)Δ
(Notice I multiplied the Δ by π (according to Rule 1 above) and then by (2R) (according to Rule 2) above.)
Relative uncertainty = absolute uncertainty / measured value, so:
Relative uncertainty in area = π(2R)Δ / (πR²)
= 2Δ/R
= 0.2 × 10^4 cm / (1.8 times; 10^4 cm)
(which is about 11%)
The answer should be a, repeat the the results many times.

Answer:
A. A perceptual region does not have any formal agreed upon boundaries. A formal region does have defining boundaries.
Explanation:
According to Geographers, the world is divided into three main different regions and it includes the following: Formal, Functional, and Perceptual regions.
The formal region is a term that describes an area that has its explicit boundaries, including widely accepted language and political process and structure
On the other hand, a Perceptual region is a term that describes an area in terms of how people or individuals see the area.
