Answer:
Using the 30-60-90 triangle to find sine and cosine
sin(60 degrees) = 2√3 4.
sin(60 degrees) = √3 2.
sin(30 degrees) = 2 4.
sin(30 degrees) = 1 2.
cos(60 degrees) = 2 4.
cos(60 degrees) = 1 2.
cos(30 degrees) = 2√3 4.
cos(30 degrees) = √3 2.
It’s not a function because the line folds over itself
The population of the town in 36 years would be 8000.
<h3>What would be the population of the town in 36 years?</h3>
The formula that can be used to determine the town's population is:
FV = P (1 + r)^n
Where:
- FV = Future value
- P = Present value
- R = rate of growth = 100%
- N = number of years = 36/9 = 4
500 x 2^4 = 8000

Lateral surface area of a cylinder: 2πrh, r is the radius, h is the height.
area of the top and bottom circle: πr²
when h=2r, the total surface area is:
2πr(2r)+πr²+πr²=6πr²
the answer is 6πr²
