Answer: The coordinates of triangle A'B'C',
A'≡(3/2, -9/4)
B'≡(-3, 9/4)
C'≡(3/2, 9/4)
Step-by-step explanation:
Since, the rule of transforming the triangle ABC by the scale factor -3/4,
Thus, the coordinates of the transformed triangle A'B'C',
So, the coordinates are A'≡(3/2, -9/4)
B'≡(-3, 9/4)
C'≡(3/2, 9/4)
Answer:I believe the answer is true but not 100% sure Hope this helped
I'm not quite sure if I'm right because i am barely learning that but the answer would be
2sec²θ
idk sorry.. hope the answer is right.
Answer:
(last/fourth option)
Step-by-step explanation:
Answer:
3,165.12 square meters
Step-by-step explanation:
To find the surface area of a cylinder, first separate the shapes you must find the area of. In this case, you need to find the areas of two circles and one rectangle (the height).
The two circles can be found using the equation: a = pi(r^2). r means radius!
12 squared is 144, which, multiplied by pi, is 452.16 square units. Because there are two circles, you can multiply this area by two to get the area of both: 904.32.
The rectangle can be found by multiplying the circumference of the circle by the height of the cylinder. The circumference can be found with the equation: c = 2pi(r). The circumference of this cylinder's base is 75.36, which, multiplied by the height of the cylinder, is 2,260.8.
Now that you have both the area of the circles and the side, you can add them both together and get the surface area.
