Answer:
162m²
Step-by-step explanation:
distance from corner to center = 1/2 of the diagonal
all sides are equal, and this has 4 sides, so it is a square
9m = 1/2 of diagonal
multiply both sides by 2 to isolate the diagonal
18m = diagonal
area of square = length²
length * √2 = diagonal
given the diagonal, we can find the length and then the area
length * √2 = diagonal
divide both sides by √2 to find the length
18m/√2 = length ≈12.7
square the length to find the area
area = 162 m²
Answer:
(3,-3)
Step-by-step explanation:
Octahedron has 8 faces, icosahedron has 20 faces. Therefore the answer is dodecahedron, it has 12 faces.
Answer:
A model that shows a pitcher holding 8 times the amount of a glass
Step-by-step explanation:
I would need a picture of the models, but I think I can still help.
Any model that shows a pitcher holding 8 times as much as a glass is the correct model. Be sure to read carefully so you pick the right model.
<u> P = 2(L +W)</u>
Divide each side of the equation by 2 : P/2 = L + W
Subtract W from each side : <em> P/2 - W = L</em>
