A 12-foot wall measures 2.5 inches on a scale drawing. In the drawing, a second wall is 9 inches long. What is the actual length of the second wall?
The length of the second wall is feet.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

the answer is 0.000652422

but if you ment to ask what is 6131 divided by 4, it is 1532.75.
