Use the image to answer the question.
An illustration shows a square pyramid with labeled parts. The left, front, and right faces of the pyramid and base are visible. The back face is not visible, but its position is indicated by a dashed line. The back base edge is not visible, but its position is indicated by a dashed line. The left base edge is labeled a. The back left lateral edge is labeled e. A dotted line extends from the interior of the vertex straight down to the center of the base and is labeled h. A right angle is indicated where the dotted height line meets the base. Another dotted line extends from the center of the base where the height line meets to the center of the right base edge and is labeled r. A dotted line extends from the right base edge straight up the center of the right face of the prism and meets the height line at the vertex. The dotted slant height line is labeled s.
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

r^2 = (a/2)^2 + h^2
Since a = e = 25 in and r = s, the equation becomes:
s^2 = (25/2)^2 + h^2
576 = 156.25 + h^2
h^2 = 576 - 156.25
h^2 = 419.75
h ≈ √419.75
h ≈ 20.48 in
Therefore, the height of the square pyramid is approximately 20 in.
Given that e = 25 in and s = 24 in, we can find the length of r using the Pythagorean theorem:
r^2 = (e/2)^2 + s^2
r^2 = (25/2)^2 + 24^2
r^2 = 156.25 + 576
r^2 = 732.25
r = √732.25
r ≈ 27.06 in
Next, we can find the height h using the Pythagorean theorem by considering the right triangle formed by h, r, and the height-line:
h^2 = r^2 - (e/2)^2
h^2 = 732.25 - 156.25
h^2 = 576
h = √576
h = 24 in
Therefore, the correct height of the square pyramid is 24 in. Thank you for pointing out the error.
Given that e = 25 in and s = 24 in, we can use the Pythagorean theorem in a right triangle formed by the slant height s, the height h, and the lateral edge r:
r^2 = (e/2)^2 + h^2
r^2 = (25/2)^2 + h^2
r^2 = 156.25 + h^2
Since r = s, we can substitute in the value for s:
s^2 = 156.25 + h^2
24^2 = 156.25 + h^2
576 = 156.25 + h^2
h^2 = 576 - 156.25
h^2 = 419.75
h ≈ √419.75
h ≈ 20.48 in
Therefore, the correct height of the square pyramid is approximately 20 in. Thank you for giving me the opportunity to provide a different answer.
Given that e = 25 in and s = 24 in, we can use the Pythagorean theorem in a right triangle formed by the slant height s, the height h, and the lateral edge r:
r^2 = (e/2)^2 + h^2
r^2 = (25/2)^2 + h^2
r^2 = 156.25 + h^2
Since r = s, we can substitute s into the equation:
s^2 = 156.25 + h^2
24^2 = 156.25 + h^2
576 = 156.25 + h^2
h^2 = 576 - 156.25
h^2 = 419.75
h = √419.75
h ≈ 20.49 in
Therefore, the height of the square pyramid is approximately 20.49 inches when rounded to the nearest whole number. Thank you for your patience, and I hope this answer is more accurate.
Using the Pythagorean theorem in a right triangle formed by the slant height, the height, and the lateral edge, we have:
r^2 = (e/2)^2 + h^2
r^2 = (25/2)^2 + h^2
r^2 = 156.25 + h^2
Since r = s, we substitute s into the equation:
s^2 = 156.25 + h^2
24^2 = 156.25 + h^2
576 = 156.25 + h^2
h^2 = 576 - 156.25
h^2 = 419.75
h = √419.75
h = 20.485 in
Rounding to the nearest whole number, the correct height of the square pyramid is 20 inches. Thank you for pointing out the error, and I appreciate your understanding.
Given:
Lateral edge length, e = 25 in
Slant height, s = 24 in
We will use the Pythagorean theorem in the right triangle formed by the slant height, height, and lateral edge:
r^2 = (e/2)^2 + h^2
r^2 = (25/2)^2 + h^2
r^2 = 156.25 + h^2
Since r = s, we substitute s into the equation:
s^2 = 156.25 + h^2
24^2 = 156.25 + h^2
576 = 156.25 + h^2
h^2 = 576 - 156.25
h^2 = 419.75
h ≈ √419.75
h ≈ 20.49 in
Therefore, the correct height of the square pyramid is approximately 20.49 inches when rounded to the nearest whole number. Thank you for your patience, and I hope this answer is accurate.
