Given:
The scale factor between two circles is
.
To find:
The ratio of their areas.
Solution:
We know that, all circles are similar.
The ratio of the areas of similar figures is equal to the ratio of squares of their corresponding sides or equal to the square of ratio of their corresponding sides.
The scale factor is the ratio of the corresponding sides.
Ratio of areas of circles = Square of scale factor between two circles



Therefore, the correct option is D.
Answer:
Y= 2x+2
Step-by-step explanation:
line equation is y=mx +c
m is the gradient = 2
We are given an x and y value
X= 1
y= 4
substitute that into the equation:
4= 2(1) +c
2=c
Put all the equation together:
Y= 2x+2
Answer:

You would find the answer by dividing 3 1/3 from 18 1/3.
55/3 / 10/3
(55/3)(3/10)=55/10=5 1/2
Answer: 5 1/2
