If the diameter is 2 feet, the circumference, 2(pi)r is equal to 6.28 feet. Each mile is 5,280 feet so the wheel must rotate 840.76 times to cover one mile. (ps - I'm not sure what you meant by the note to use 227 for pi.)
There are 3 primary colors so there are 3 on the color wheel.
No, complimentary colors are across from each other on the color wheel.
The standard color wheel generally consists of 12 colors. A complemtary color is directly opposite of another color. So the standard color wheel would have 6 pairs of complementary colors.
blue, red, and yellow
There are three. Red, yellow, and blue.
5000 revolutions in 11000m = 1 revolution every 2.2m Circumference is 2.2m Circumference is diameter times pi 2.2m dividied by pi divided by 2 (to go from diameter to radius) = 35.014cm
A wheel 2 feet in diameter turning 10000 revolutions per hour is going, at the rim, 17.45 feet per second, or 25.6 miles per hour.

The circumference of an 8-inch diameter wheel = d*pi = 8*pi. Each revolution will advance the wheel by one circumference, so 2000 revolutions per minute would be 2000 * 8 * pi = 1600pi feet per minute.
Its 16
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.
If the diameter is 700 mm then the radius is 700/2 = 350mm The circumference of the circle is 2πr = 2π.350 = 2199.115 mm 1 kilometre = 1000 metres = 1000000 mm : 2km = 2000000mm Number of revolutions = distance travelled ÷ circumference of wheel. 2000000 ÷ 2199.115 = 909. 46 revolutions
0.42 * 13.2=5.544
NO. The smaller the wheel the more revolutions it turns if both are driven at the same speed. So, the smaller the wheel the faster it turns.
It will travel: 50*12*pi = 1885 inches rounded to the nearest integer
