a pie is cut into 8 equel slices. if a person wants 0.75(pie sign) centimetre of crust, about how many pieces should they take?
This question is bull-schnot. Too many variables, no adherent context. Quit posting useless questions for those students who are trying to study.
To determine how many pieces the person should take to get 0.75(pie sign) centimeters of crust, we need to calculate the total amount of crust in the pie and divide it by the thickness of the crust the person wants.
Here's the step-by-step calculation:
1. First, let's find the circumference of the pie. The circumference of a circle can be calculated using the formula: C = 2(pie sign)r, where "r" represents the radius of the pie. Since the pie is cut into 8 equal slices, the angle of each slice is 360 degrees divided by 8, which is 45 degrees.
2. Now, let's calculate the radius of the pie. Since each slice cuts across the center of the pie, the angle between two radii of the pie is 45 degrees. Drawing a line from the center of the pie to the edge of a slice creates a right triangle. The angle at the center of the pie is 45 degrees, and the adjacent side of the triangle is half of the length of the slice. Therefore, the adjacent side (radius) is equal to the length of the slice divided by the square root of 2.
3. Once we have the radius, we can calculate the circumference of the pie using the formula mentioned earlier.
4. Finally, we divide the desired thickness of the crust (0.75(pie sign) centimeters) by the circumference of the pie to find out how many pieces the person should take.
Let's conduct the calculations:
1. The angle of each slice = 360 degrees / 8 = 45 degrees.
2. Length of each slice / radius = 45 degrees => radius = length of each slice / √2.
3. Circumference of the pie = 2(pie sign) * radius.
4. Number of pieces to take = desired thickness of crust / circumference of the pie.
By following these steps, you can obtain the precise answer to the question.
