To find the length of r, we will use the Pythagorean theorem.
Using the slant height and the height of the triangular face (since the triangular face and the height of the pyramid form a right triangle), we can set up the equation:
r^2 = s^2 - (0.5e)^2
Plugging in the given values:
r^2 = 24^2 - (0.5*25)^2
r^2 = 576 - 6.25
r^2 = 569.75
Taking the square root of both sides to find r:
r ≈ √569.75
r ≈ 23.86
Now that we have the radius, we can use the Pythagorean theorem again to find the height of the pyramid.
Using the radius and the lateral edge length as the two legs of a right triangle, we can set up the equation:
h^2 = s^2 - r^2
Plugging in the given values:
h^2 = 24^2 - 23.86^2
h^2 = 576 - 569.75
h^2 = 6.25
Taking the square root of both sides to find h:
h ≈ √6.25
h ≈ 2.5
Rounding to the nearest whole number, the height of the pyramid is about 3 inches.
For the square pyramid, the lateral edge length, e, is 25 in., and the slant height, s, is 24 in.
Find the height of the pyramid, h. Round the answer to the nearest whole number. Hint:
Before finding the length of h, you will first need to find the length of r.

Incorrect, try again
Apologies for the mistake. Let's try again.
To find the height of the pyramid, we can use the Pythagorean theorem with the slant height and the radius of the base.
First, let's find the length of the radius, r:
r^2 = s^2 - (0.5e)^2
Plugging in the given values:
r^2 = 24^2 - (0.5*25)^2
r^2 = 576 - 6.25
r^2 = 569.75
Taking the square root of both sides to find r:
r ≈ √569.75
r ≈ 23.86
Now that we have the radius, we can find the height, h, of the pyramid using the Pythagorean theorem. We have a right triangle with the height, radius, and slant height as its sides:
s^2 = r^2 + h^2
Plugging in the given values:
24^2 = 23.86^2 + h^2
576 = 569.75 + h^2
6.25 = h^2
Taking the square root of both sides to find h:
h ≈ √6.25
h ≈ 2.5
Rounding to the nearest whole number, the height of the pyramid is approximately 3 inches.

I apologize for the confusion, but the height of the pyramid is not 23 inches. It is indeed approximately 3 inches.
