Answer:
The area of the new circle is 
Step-by-step explanation:
Given:
radius of the circle = 3 in.
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared.
Let
z-----> the scale factor
x-----> the area of the enlarged circle
y-----> the area of the original circle
So;

In this problem we have
----> the scale factor
The area of the original circle is equal to

Now substituting value of y and solve for x we get;

Hence Area of the new Circle is 
Also The area of the enlarged circle is 16 times the area of the original circle.
Answer:
(84/18, 14/3). These are the same as 42/9
Option a:
is the solution to the system of equations.
Explanation:
The equations are
and 
Equating these two equations, we have,

Taking LCM and multiplying both sides by 5, we get,

Simplifying , we get,

Substituting the value of x in
, we get,

Thus, the solution is 
Changing the solution from fraction to decimal, we get, 
Thus, the solution is 
Hence, option a is the correct answer.
Answer:
1. 0.3 m
2. yes
Step-by-step explanation:
The computation is shown below:
Given that
Measurement of space = 0.8m
measurement of the shelves = 30 cm = 0.3 m as 1 m = 100 cm
So for 30 cm it would be
= 0.30 ÷ 100
= 0.3 m
Based on the above information,
1. The number of meters wide for the shelf to buy is 0.3 m
2 And yes it is fitted in the house
