Answer:
Surface Area of the Cylinder is 1156.11
Step-by-step explanation:
To find the Surface Area of a Cylinder, the equation given is A = 2πrh+2πr2
Given the radius and height of the cylinder, we plug those numbers into the equation to get;
A = 2π(8)(15)+2π(8)2
= 1156.11
Answer:
<-8.60, -12.29>
Step-by-step explanation:
Pictuas shown in the attached image to represent the direction 35 west of south of the vector velocity and understand which trig function to use for its components. See the actual vector velocity as the hypotenuse of a right angle triangle.
The vertical component would be pointing down, and its magnitude would result from the use of the cosine of the angle (since it involves the adjacent side to the angle):
15 * cos (35) = 12.29
the horizontal component is pointing left, and its magnitude would be the result of the use of the sine of the angle (it involves the opposite side to the angle):
15 * (sin*35) = 8.60.
Using the fact that the components are pointing down and pointing left, we need to include a negative sign to both.
Therefore the component form of the vector is: <-8.60, -12.29>
Answer and Step-by-step explanation:
2.
The value of x is equal to 148. This is because of the vertical angles theorem.
The vertical angles theorem states that when two angles are vertical to each other (such as the example in this problem), then they are equal to each other.
5.
We know that a line has a angle of 180 degrees. So, to find x, we subtract everything from 180.
180 - 125 - 30 = x
25 = x
8.
We know that given angle in total is equal to 89 degrees. So, to find x, we subtract everything from 89.
89 - 12 - 29 = x
48 = x
