Answer:
36
Step-by-step explanation:
Answer:
³/2 (1.5)
Step-by-step explanation:
∆DEF was enlarged to get ∆ABC. The scale factor would be:
The ratio of any of the side length of ∆ABC to the corresponding side length of ∆DEF.
Thus,
BC:EF = 12:8
= 12/8
= 3/2 = 1.5
Scale factor from ∆DEF to ∆ABC is ³/2 or 1.5
The lateral area of the pyramid is 108.49 cm^2. The lateral surface area is the total of all of each side's area of a three-dimensional figure and it has a different method to calculate it. First, you must find the triangle's height by using the Pythagoras formula resulting 7.41 cm ( =squareroot(8^2-3^2)), thus, you can find the lateral area using the square and triangles area formula (108.49=(8*8) + 4*(0.5*3*7.41))<span>.</span>
a < b
the < means that the first letter is less than the second letter. So this equation is saying a is less than b.
If a is less than b, that also means that b is greater than a.
The correct answer would be B.
