Question

I need part C of this problem ASAP
A radar screen for air traffic control is in the shape of a circle. The screen has a diameter of 24 inches.

A. What is the area of the screen to the nearest square inch?


B. The radar screen is much smaller than the actual distance. The scale is 6 inches : 25 nautical miles. To the nearest square nautical mile, what is the area of the circular region covered by the radar?


C. The base of the radar screen is a square with a circle inside it. To the nearest square inch, what is the area of the part of the base that is not within the circle? Explain your answer.

Answer 1

Answer:

277 in^2

Step-by-step explanation:

• You know that the area of the circle, which is approximately 452in^2. (Because you do (3.14(12^2)) to get the area)

• Calculate the area of the square (since it's a square all 4 sides are even): 27 x 27 = 729 in^2

• Subtract 452 from 729 to get 277 in^2.

Since you only need to know the area of how much of the base is in the circle, you only need to calculate the two areas and subtract them to get the remaining area = the total area in which the circle isn't in.

I hope this was helpful
