Answer:
1187.52
Step-by-step explanation:
A=2πrh+2πr2=2·π·9·12+2·π·92≈1187.52202
The answer is D. dividing both sides by 4 isolates the variable
A rotation is a transformation that preserves figure shape, figure sizes, angles and lengths.
Therefore,
- option A is false, because rotation preserves sizes;
- option B is false, because rotation doesn't change the figure size;
- option C is true, because rotation preserves figure angles;
- option D is true, because rotation preserves lenghts of segments.
Answer: option C and D.
