Answer:
A (the marked answer is correct)
Step-by-step explanation:
The result of a single refection will look like the reverse of the letter Z, so the only possibilities are choices A and C.
Since the horizontal lines are still horizontal, the reflection must be across a horizontal or vertical line. If the reflection is across a horizontal line, the image will be vertically aligned with the preimage. If the reflection is across a vertical line, the image will be horizontally aligned with the preimage.
Choice A is horizontally aligned with the preimage. Choice C is not aligned either way. (It is a "glide reflection.")
Image A is the result of reflection across the y-axis.
Answer: x < 8
Step-by-step explanation:
R = 9
h = 36
Pp = ?<span>area of a circle</span>
l = ? surface of the wheel
Pb = lateral surface
Pc - total surface
Pp = πr² = 9²*π = 81π (unit²)
l = 2πr = 2*9*π = 18π (unit)
Pb = l*h = 18π * 36 = 648 π(unit²)
Pc = 2Pp + Pb = 2* 81π + 648π = 162π + 648π = 810π(unit²)
Answer total area equal to 810π (unit²)
