Answer:
40 or 16+6+6+6+6
Step-by-step explanation:
To find the surface area of a 3d figure, we can imagine all of its faces laid down on a flat plane. In this case, we would have a square, and four congruent triangles. Now all we have to do is find the areas of each shape and add them up.
4 is the base of the pyramid, so it's also the square's side length. Since a square has four equal sides, our square's length and width are both 4.
4*4 = 16
For every triangle we have, the base is 4 and the height is 3. The area of a triangle can be found using the formula A=(bh)/2. We plug in the values:
A = (4*3)/2
A = (12)/2
A = 6
Since we have 4 triangles, the surface area is:
16+6+6+6+6 = 40
6 3/4 I think is a possible answer
Step-by-step explanation:
Thr triangles are similar if any two sides are proportional.
In this, we cannot see any proportional sides, like
DU should be proportional to UT, it is not.
SU should be equal to UE ,it is not.
So, The triangles are not similar.
Hope it helps :)
Answer:
G
Step-by-step explanation:
-3
substitute the value of g into f, evaluate the result function by replacing x with 4 in the function.
Answer:
72.25
Step-by-step explanation:
Triangles are 1/2(base x height), or (base x height) / 2.
17 x 8.5 = 144.5
144.5 / 2 = 72.25
