1. The science club constructed a pyramid with a square base out of paper clips. The height of the pyramid is 2.5 feet. One side
elena-14-01-66 [18.8K]

Answer:

Part 1) The slant height of the pyramid is 2.80\ ft

Part 2) The length of the third side of the window is 20.78\ in

Part 3) The building's slant height is 53.85\ ft

Step-by-step explanation:

Part 1) we know that

To find out the slant height of the pyramid, apply the Pythagorean Theorem

Let

l ----> the slant height of the pyramid

h ---> the height of the pyramid

b ---> the length side of the square base

l^2=h^2+(b/2)^2

we have

h=2.5\ ft\\b=2.5\ ft

substitute the given values

l^2=2.5^2+(2.5/2)^2

l^2=2.5^2+(1.25)^2

l^2=7.8125

l=2.80\ ft

Part 2) Let

c ----> the hypotenuse of a right triangle (the greater side)

a ---> the measure of one leg of the right triangle

b ---> the measure of the other leg of the right triangle

Applying the Pythagorean Theorem

c^2=a^2+b^2

we have

c=24\ in\\a=12\ in

substitute the given values and solve for b

24^2=12^2+b^2

b^2=24^2-12^2

b^2=432

b=20.78\ in

Part 3) Let

l ----> the building's slant height

h ---> the height of the building

r ---> the radius of the base of the building

Applying the Pythagorean Theorem

l^2=h^2+r^2

we have

h=50\ ft\\r=20\ ft

substitute the given values

l^2=50^2+20^2

l^2=2,900

l=53.85\ ft
