Well not all lines are lines of symmerty, because if you draw a let's say a rectangle on a piece of paper and draw a diagonal line through it, well the two sides don't really lie perfectly on one another!!
To work out the circumference you have to multiple pi by the diameter . since pi is 3 and the diameter is 9. you have to multiply 9 by 3 to work it out.the answer would be 27. hope this helps you
The answer to the question is (x + 3)
The hundreds place has to be 2 because 4 or 5 can't round to 2. Now we have to determine the tens place. 4 rounds down and 5 rounds up so if we put 5 in the 10s place the 2 would round up to 3. If we put 4 in the 10s place the 2 it rounds down and the 2 remains 2. So the answer must be
245
This rounds down to 200
Answer: x = 3
