Approx 2.1 cm.
The diameter is the circumference divided by the constant, Pi (3.14).
The diameter of a circle that has a circumference of 125 centimeters is: 39.79 cm (circumference divided by Pi = diameter).
There are 2.54 centimetres in one inch. Therefore, rounded to two decimal places, 66 centimetres is equal to 66 / 2.54 = 25.98 inches.There are 2.54 centimeters in one inch. Therefore to get amount of inches in centimeters, value in centimeters has to be divided by amount of centimeters in one inch:66 centimeters = [centimeters] / 2.54 = 66 / 2.54 = 25.98 inches
66 inches = 167.64 centimeters.
volume of a cylinder = pi*radius2*height Rearrange the formula: radius = the square root of (volume divided by pi*height) radius = the square root of (142/pi*8.5) radius = 2.306002496 centimeters or 2 cm to the nearest cm.
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.
pi is not divided into anything - unless you specify pi/2 or pi/3.6
