Answer:
C) 101.5 pi in^2
Step-by-step explanation:
A cylinder's area is found by next formula:
This is because the cylinder has two circle bases and its lateral area is a rectangle whose base is the perimeter of a circle and whose height is the cylinder's height. My last step was to take the common factor.
From the figure you get the cylinder's height and the base diameter's length, which is double of radius'. Since we need "r":
Now, we replace height and radius in the formula:
Answer:
now one will understand except you because you place the pictures where you cant see the first part
The terminal point determined by an angle is given by the point on the circumference of the unit circle such that the angle between the radius of the circle and the x-axis is the given angle.
Given the angle
This angle is equivalent to the angle
To find the terminal point, we note that the radius of the unit circle at that point makes a right angle with the coordinates of the terminal point.
We also note that angle
is on the 2nd quadrant of the coordinate axis. This means that the x-value of the terminal point is negative while the y-value is positive.
We also note that the radius of a unit circle is 1.
To find the x-coordinate of the terminal point, we use the relation
Similarly to find the y-coordinate of the terminal point, we use the relation
Therefore, the <span>coordinates of the terminal point determined by T = 20 pi /3 are
