Answer:
The total surface area of this square pyramid is
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to
we have
----> the length side of the square base
----> the height of the triangular faces
substitute the values
The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).
Slope (m) =
<u>To find the missing coordinate r:</u>
Slope formula:
Substitute the given values in the formula.
Do cross multiplication.
40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.
