The area of a circle uses the radius of a circle, which is 1/2 the diameter.
In the calculation the radius is squared.
Since the diameter of the larger circle is twice as large the radius would be 2 times.
2 squared would be: 2^2 = 4
This means the area of the larger circle is 4 times larger which would make the ratio 4:1
5+3x/4
5x+1/2(1/4+10). Distributive property
5x+x/8+5. Combine like terms
5+3x/4
Answer:
17
Step-by-step explanation:
Answer:

Step-by-step explanation:
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the Triangle Inequality Theorem
1) 
solve for n

Rewrite

2) 

therefore

53280 miles. If you multiply the mps by seconds in a minute (60) then minutes (48) you can get this answer easily
