Adiagram of a plane drawn to the scale of 0.5 inch equals 80 feet if the length of the diagram is 4.5 inches the actual length of plane is

Step-by-step explanation:

You need to analize the information provided in the exercise.

First, you know that the scale of the diagram of the plane is:

Then, knowing that the lenght of the diagram is 4.5 inches, you need multiply this lenght by 80 feet and divide the product by 0.5 inches, in order to find the   actual length of the plane.

Therefore, you get:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
