Yes.
1467-776=691
Which means 776 believed the country was protected and 691 believed the country wasn't.
Answer: The angle is 105 degrees. This angle along with the 75 degree angle make a straight line , 180-75 = 105 degrees
We need to see the "given system".
The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂
Since the area of a circle is
![\pi r^{2}](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E%7B2%7D%20)
,
SA = 2*(
![\pi r^{2}](https://tex.z-dn.net/?f=%20%5Cpi%20r%5E%7B2%7D%20)
) + A₂
Since the area of the side is height * the circumference of the circle or A₂ = h *
![2 \pi r](https://tex.z-dn.net/?f=2%20%5Cpi%20r)
, then SA must be;
SA =
![2* \pi (r ^{2} )+h*2 \pi r](https://tex.z-dn.net/?f=2%2A%20%5Cpi%20%28r%20%5E%7B2%7D%20%29%2Bh%2A2%20%5Cpi%20r)
SA =
![2* \pi (4 ^{2} )+5*2 \pi (4)](https://tex.z-dn.net/?f=2%2A%20%5Cpi%20%284%20%5E%7B2%7D%20%29%2B5%2A2%20%5Cpi%20%284%29)
SA =
![32* \pi+80 \pi](https://tex.z-dn.net/?f=32%2A%20%5Cpi%2B80%20%5Cpi%20)
SA ≈ <span>351.858377202</span>
