Answer:

Step-by-step explanation:
The total surface area can be calculated using the formula

From the diagram

We plug in these values to get;
![S.A=2[5(5)+5(10)+5(10)]](https://tex.z-dn.net/?f=S.A%3D2%5B5%285%29%2B5%2810%29%2B5%2810%29%5D)
![S.A=2[25+50+50]](https://tex.z-dn.net/?f=S.A%3D2%5B25%2B50%2B50%5D)


You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is

By following the formula, cos=3/5 then:

Multiply everything (inside the square

root) by 5


Then just simplify

The answer is Square root of 20 over 5
Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h
R = 27 cm
H = 37 cm
Take away the Pi seeing as you want to keep it in terms of Pi
2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B
Answer: 12
11x - 2 = 130
11x = 130 + 2
11x = 132
x = 132/11
x = 12
Now with value x the angle will be 130 and using converse of corresponding angles theorem line v and u will be parallel
