Circumference= 2πr
Circumference= perimeter
14.28km= 2(3.14)r
14.28= 6.2831853072r
divide both sides by 6.2831853072
2.27= r
ANSWER: The radius is 2.27km
Hope this helps! :)
Answer: 
Step-by-step explanation:
To find the function h(x), you need to subtract the function
and the function
.

Distribute the negative sign:

Now you can add the like terms:

Therefore, you get that the function h(x) is:

Given:
In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.
To find:
The length of the side KM to the nearest tenth of a centimeter.
Solution:
In a right angle triangle,

In the given right triangle KLM,



Multiply both sides by 123.



The measure of side KM is 100.8 cm.
Therefore, the correct option is (2).
Answer: yes it is equivalent!
Step-by-step explanation:
all you do is take away the parentheses and then it is the same exact thing!
11. you do 3x3=9 then plus 9+2 = 12 then 12 x 12 = 144
sorry idk 10.
