Answer:
Two shapes are similar when they have the same shape while their sizes may be the same or different
Therefore, two similar shapes are shapes that have a relationship such that the dimensions of one of the shapes can be obtained from the dimensions of the other shape by multiplying by a scale factor
All circles have the same shape and are defined by their center and radius
Given circle with center at 'x' and radius 'r' and circle with center 'y' and radius 's', then there exist a scale factor a = s/r such that we have;
r × a = s
Where a = s/r, we get;
r × s/r = s
We can therefore, obtain a circle with with the same size as the circle with center 'y' and radius 's' by multiplying the radius of the circle with center at 'x' and radius 'r' by a
Therefore the circle with center at 'x' and radius 'r' is similar to the circle with center 'y' and radius 's'

Answer:
It is better to buy 20 g of flour 3 for 3.50
Step-by-step explanation:
It is given that 20g of 3 for 3.50
It means 3 packets of 20 g is 3*20 =60
So, 60g is for 3.50
So, 1 g =
=0.05833 per gram.
Now, let's find unit rate for 40 g of 2 for 9.
2 packets of 40 gram = 2* 40 =80 grams
So, 80 grams costs 9
So, 1 gram =
=0.1125
So, it is better to buy 20 g of flour 3 for 3.50
