Hello :)
The first one would be a rotation because it was easily rotated upward , it looks like it was rotated maybe 90°, The second one would be translation because it is simply moved upward and moved slightly to the right without be resized, rotated, or anything. The third one would definitely be a reflection because it appears to be flipped across the x axis. The fourth one i'm not really sure but i'm going to guess it is a rotation because it is turned in a different direction from the original figure.
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
Answer:
Sis sis did six sxos did did
Step-by-step explanation:
Answer: 90 degrees
Step-by-step explanation:arcs qr and ts are vertical angles so they are the same amount. then take half the circle 180 degrees subtract 90 and that's your answer since 90 is half of 180 90 is your final answer
