Answer:
50 meters
Step-by-step explanation:
The area of a circle is
, so assuming that
is 3.14, we can make the equation
.
Assuming the radius is r, which is 4, we can substitute the values into the equation.
![3.14 \cdot 4^2\\3.14\cdot16\\50.24](https://tex.z-dn.net/?f=3.14%20%5Ccdot%204%5E2%5C%5C3.14%5Ccdot16%5C%5C50.24)
This question is asking for the area to the nearest square meter so rounding 50.24 to the nearest square meter results in 50.
Hope this helped!
We have to evaluate the summation of (3n+2), with n ranging from 1 to 14. Let's write all the terms of the sum for each value of n:
n=1:
![3n+2 = 3\cdot 1+2=5](https://tex.z-dn.net/?f=%203n%2B2%20%3D%203%5Ccdot%201%2B2%3D5)
n=2:
![3n+2 = 3\cdot 2+2=8](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%202%2B2%3D8)
n=3:
![3n+2 = 3\cdot 3+2=11](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%203%2B2%3D11)
n=4:
![3n+2 = 3\cdot 4+2=14](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%204%2B2%3D14)
n=5:
![3n+2 = 3\cdot 5+2=17](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%205%2B2%3D17)
n=6:
![3n+2 = 3\cdot 6+2=20](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%206%2B2%3D20)
n=7:
![3n+2 = 3\cdot 7+2=23](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%207%2B2%3D23)
n=8:
![3n+2 = 3\cdot 8+2=26](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%208%2B2%3D26)
n=9:
![3n+2 = 3\cdot 9+2=29](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%209%2B2%3D29)
n=10:
![3n+2 = 3\cdot 10+2=32](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%2010%2B2%3D32)
n=11:
![3n+2 = 3\cdot 11+2=35](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%2011%2B2%3D35)
n=12:
![3n+2 = 3\cdot 12+2=38](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%2012%2B2%3D38)
n=13:
![3n+2 = 3\cdot 13+2=41](https://tex.z-dn.net/?f=3n%2B2%20%3D%203%5Ccdot%2013%2B2%3D41)
n=14:
![3n+2 = 3\cdot 14+2=44](https://tex.z-dn.net/?f=%203n%2B2%20%3D%203%5Ccdot%2014%2B2%3D44)
Now, let's sum all the terms together, and we get:
Answer:
7/11
Step-by-step explanation:
7y +6+4y+13=26
firstly collect like terms
7y+4y+6+13=26
11y+19=26
11y=26-19
11y=7
then divide through by 11
y=7/11
