Question

During basic training Kevin learns how to read distances on a radar what should Kevin conclude is the distance around largest circle on the radar screen. Please help :(

Answer 1

The largest circle on a radar screen represents the maximum range of the radar system.

Step-by-step explanation:

Physics: Reading Distances on a Radar

In basic training, Kevin learns how to read distances on a radar screen. The largest circle on a radar screen represents the maximum distance that the radar can detect. This distance is determined by the capabilities of the radar system, including its power and sensitivity. Therefore, Kevin should conclude that the largest circle on the radar screen represents the maximum range of the radar system.

Example: If the radar system has a maximum range of 100 kilometers, the largest circle on the radar screen would represent this distance. Objects beyond this range would not be detected by the radar.

Answer 2

H) 63.585

Step-by-step explanation:

Using the graph, we can estimate that the radius is about 4.5 units.

Using the formula of finding area of a circle, pi x radius^2, we can substitude 4.5 as r and 3.14 as pi.

So, 4.5^2 x 3.14 is about 63.585 units.
