yes, they are similar because each side length is equal making it an equilateral triangle. As a result, the two triangles are similar.
Answer:
(x, y) = (15, 4)
Step-by-step explanation:
Segments created by parallel bases of the triangle(s) are proportional.
We observe that the lower segment is 1/3 the length of the upper segment.
5 = 1/3x
15 = x . . . . . . multiply by 3
__
y = (1/3)(12)
y = 4
When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4
Volume of a cylinder= π r² h
Diameter(D)= 2r
D= 225h
D= 225(2214)= 498150 ft
498150/2=r
r= 249075 ft
h= 2214 ft
V= π (249075²)(2214)
V= π(62038355625)(2214)
V ≈ 4.32*10^(14) ft³
Answer:
The volume is about 4.32*10^(14) cubic feet.
(If I got the numbers wrong for the height or diameter please let me know and I'll fix it later today because this answer seems really large and your numbers are written weird in your question. I attached an image of how your question appeared to me)
