Answer:
Lateral areas have ratio of 4:1
Volumes have ratio of 8:1
Step-by-step explanation:
There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of , the ratio of any surface area type measure is always this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of .
Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of which if you simplify it, it is , which is . The ratio of the heights are .
Now we can apply those rules to this ratio, the ratio of lateral areas would then be , which is . the ratio of volumes would be , which is
Answer:
the answer to this is b( 2,-8)
Answer:
Step-by-step explanation:
The center of the circle whose diameter has endpoints (18, -13) and (4, -3) will be the midpoint of the coordinates.
The ormua for calculating mid point is expressed as;
M(X,Y) ={(x21+x2/2, y1+y2/2}
X= x1+x2/2
Y = y1+y2/2
From the coordinates
x1 = 18 x2 = 4
X= 18+4/2
X = 22/2
X = 11
y1= -13, y2= -3
Y = -3-13/2
Y = -16/2
Y = -8
Hence the required centre will be at (11,-8)
It's the 4th choice.
The solutions will be the points of intersection of the 2 graphs.
Answer:
Its 58
Step-by-step explanation:
Because the bigger triangle is a dilation of the smaller one. In other words only the sides get bigger, the angles stay the same.
