Answer: The radar scans for object in all directions around itself. A plane shape that represents "all around" is a circle.
Answer: That's related to the fact that a circle is the set of all points that have the same distance from the center.
None, but we have a couple square-shaped.
There are various reasons that manholes are shaped like a circle. For example, it is much easier to dig a circular hole.
the earth is a sphere but if you look at it as a 2d shape it is a circle
A circle perhaps
a radar uses a "parabolic" dish to capture the radio waves and because the shape is concave the waves hit the centre of the dish, the receiver is placed away from the centres facing the dish where the waves are reflected to it. The classic example is satellite dish receivers
A wedge shaped portion of a circle is called a sector.
A circle has to be ring shaped (starting and finishing at the same point) otherwise it isn't a circle.
The radar that uses a cross-shaped beam is known as a "crossed beam radar" or "cross-beam radar." This type of radar employs two intersecting beams to improve target detection and tracking accuracy by providing coverage in multiple dimensions. The cross-shaped beam pattern allows the radar to effectively scan a larger area and enhances its ability to distinguish between different targets. This design is often utilized in applications such as air traffic control and weather monitoring.
Did you know that the sun is circle shaped?
None, but we have a couple square-shaped.
This is generally referred to as a radome. The word is an amalgamation of the words "RADAR" and "dome."
