Answer:
A
Step-by-step explanation:
Answer:
The weight of the enlarged paperweight is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes (or its weights) is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x ----> the enlarged paperweight weight
y ----> the original paperweight weight
we have
substitute and solve for x
We know that
if the dilated circle <span>passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=</span>√[(4-0)²+0²]-----> d=√16------> d=4 units
the new radius is 4 units
original radius is 1 units
[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4
the answer is
<span>the scale factor of dilation is 4</span>
