(18 in) X (2.54 cm/in) = 46 cm, to the justified number of significant digits, because the value 18 has only two significant digits. If the 18 is also considered exact, the answer is 45.72 cm.
Circumference equals pi multiplied by diameter. Therefore 120 (circumference) divided by pi equals diameter. Pi is on your calculator.

A foot is exactly 30.48 centimeters.
1 centimeter equals 10 mm and 1 millimeter equals 0.1 centimeter. If you know the diameter in mm, divide by 10 to find cm.
12 inches = exactly 30.48 centimeters.
134112 centimetres exactly.
Yes. One foot is 12 inches, which is 30.48 centimeters. One inch equals exactly 2.54 centimeters.
To figure out how long a revolution is you need to find the circumference of the wheel. If the diameter is 70 centimeters, then to get the circumference you multiply the diameter by pi (3.14). That equals 219.8. centimeters. Then you convert 66 meters into centimeters, and that is 6600. Then you divide 6600 by 219.8 and get 30 revolutions.
