Step-by-step explanation:
Generally the area of a sector is mathematically represented as
![A = \frac{\theta}{360} * \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%20%5Cfrac%7B%5Ctheta%7D%7B360%7D%20%2A%20%5Cpi%20r%5E2)
Now at
and ![\theta_1 = 64^o](https://tex.z-dn.net/?f=%5Ctheta_1%20%3D%20%2064%5Eo)
![A_1 = \frac{64}{360} * 3.142 * 11^2](https://tex.z-dn.net/?f=A_1%20%3D%20%20%5Cfrac%7B64%7D%7B360%7D%20%2A%203.142%20%20%2A%2011%5E2)
![A_1 = 67.58 \ in^2](https://tex.z-dn.net/?f=A_1%20%20%3D%20%2067.58%20%5C%20in%5E2)
Now at
in and ![\theta_2 = 119 ^o](https://tex.z-dn.net/?f=%5Ctheta_2%20%20%3D%20%20119%20%5Eo)
![A_2 = \frac{119}{360} * 3.142 * 20^2](https://tex.z-dn.net/?f=A_2%20%3D%20%20%5Cfrac%7B119%7D%7B360%7D%20%2A%203.142%20%2A%20%2020%5E2)
![A_2 =415.4 \ ft^2](https://tex.z-dn.net/?f=A_2%20%3D415.4%20%5C%20ft%5E2)
Now at
and ![\theta_3 = 23 ^o](https://tex.z-dn.net/?f=%5Ctheta_3%20%3D%20%2023%20%5Eo)
![A_3 = \frac{23}{360} * 3.142 * 6.5 ^2](https://tex.z-dn.net/?f=A_3%20%20%3D%20%20%5Cfrac%7B23%7D%7B360%7D%20%2A%203.142%20%2A%20%206.5%20%5E2)
![A_3 = 8.48 \ cm^2](https://tex.z-dn.net/?f=A_3%20%20%3D%20%208.48%20%5C%20cm%5E2)
Now at
and ![\theta_4 = 360 -87 = 273 ^o](https://tex.z-dn.net/?f=%5Ctheta_4%20%3D%20360%20-87%20%3D%20%20273%20%5Eo)
![A_4 = \frac{273}{360} * 3.142 * 14.2^2](https://tex.z-dn.net/?f=A_4%20%3D%20%20%5Cfrac%7B273%7D%7B360%7D%20%20%2A%203.142%20%2A%2014.2%5E2)
![A_4 = 480.38 \ m^2](https://tex.z-dn.net/?f=A_4%20%3D%20%20480.38%20%5C%20m%5E2)
Answer:
a) so if you're looking for a then you substitute the a in the problem so the real question would be answered by simply doing this. 3 times (do this first) 6 times 3. so it would end up looking like this if you did it in your head. 6x3=18 then 18x3= 54 so the answer for ten after you did all the math would equal out to be 54.
d) so you're going to substitue the d again, for what it tells you d equals. in this case, d= a negative 2 so, 5 x do this first -2 x 4 = so if you did this in your head you would end up with -2 x 4 = -8 because anything times a negative is turned into a negative. so that is why the answer is -8 for the first part. then you multiply that answer by 5 because we all like the 5 dollar foot longs. so carry that into an answer of - 40. because we all know we want to be younger once we reach 40.
r) 5times -3 equals -15 times 2 would be... ding ding ding 30 because a negative times a negative is a positive. think of negatives this way. when you frown it's your smile upside down. ok so a frown is a negative, if you multiply a negative to a negative it's like turning your frown upside down. so you end up with a positive! ok?! so there. the secrets of life and math.
call me for the rest of the answers... this is too much to write down.

Answer:
B. ![2x^2+4x+11](https://tex.z-dn.net/?f=2x%5E2%2B4x%2B11)
Step-by-step explanation:
The given expression is
![2x^3+3x-22 \div x-2](https://tex.z-dn.net/?f=2x%5E3%2B3x-22%20%5Cdiv%20x-2)
We use synthetic division to obtain;
2 0 3 -22
2| <u> 4 8 22</u>
2 4 11 0
The quotient is ![2x^2+4x+11](https://tex.z-dn.net/?f=2x%5E2%2B4x%2B11)
The correct chice is B
Answer:
5/6 of a pound
Step-by-step explanation:
When you multiply 2/3 by 2 it will equal 4/6 making it smaller then 5/6. and divide the fraction and you will see which is smaller.
