Answer:
12mm
Step-by-step explanation:
circumference (distance around) is equal to πd.
here, if π is 3, we do 3 x the diameter, which is 4. 3 x 4 = 12mm
It is.
Notice that 0.127=127/1000, which is obviously a rational number.
9^2 (9 to the 2nd power) is 81, 9^6 (9 to the 6th power) is 531441.
Then if we multiply 81*531441 you get 43046721.
