Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
- By definition, the perimeter of the figure is the sum of the lenght of each side. Then, you must make the addition as following:
Where 
is the perimeter of the figure.
- Add the like terms, then, you obtain the following expression in simplest form:
Response:
35 : 10 = 7 : 2
Therefore 35 : 10 ≠ 7 : 5
I think it’s is -12 but I am not to sure
Answer:
75.39 in^2
Step-by-step explanation:
circumference=2πr
30.8=2(3.14)r
30.8=6.28r
4.9=r
Now that we know the radius, we can plug it in for the area equation
area=πr^2
area=(3.14)(4.9)^2
area=(3.14)(24.01)
area=75.39 in^2
