Hello!
To find the surface area of the given cylinder, we need to use the formula of the surface area of a cylinder.
The formula for the surface area of a cylinder is SA = 2πrh + 2πr².
In this formula, r is the radius and h is the height.
In the given diagram, we see that the height is 6 meters, and the radius 9 meters. With those values, we can substitute them into our formula and solve for the surface area.
In some cases, you are given the diameter. To find the radius, you would need to divide the diameter by two.
SA = 2π(9)(6) + 2π(9)²
SA = 54(2π) + 2(81π)
SA = 108π + 162π
SA = 270π
SA ≈ 848.2 m²
Therefore, the surface area of the given cylinder is choice A, 848.2 m².
Answer:
csc 2 (csc 
= csc 150 = csc 30 = csc 2)
Step-by-step explanation:
csc is in the 2nd Quadrant where only sin, and csc are positive.
csc 
but csc = 
Answer:
x= y/m-p/m-q ; m≠0
Step-by-step explanation:
y-p= m(x-q)
y/m -p/m= x-q
x= y/m- p/m +q
Answer:
It isn't necessary but having a positive coefficient for 
makes things like completing the square and factoring easier.
You can conclude that x is less than y, because a smaller number - a bigger number is equal to a negative number. :)
