a. The diameter of the tire is 23 inches.
b. The distance moved in 1 revolution is 72.26 in
c. The number of revolutions in 10,000 miles is 8768337 revolutions
The diameter of the tire is 23 inches.
Since tire stand 23 inches tall, and its height is its diameter. Then,its diameter is 23 inches.
The diameter of the tire is 23 inches.
The distance moved in 1 revolution is 72.26 in
Since 1 revolution = circumference = πD where d = diameter of tire = 23 inches.
So, the distance moved in 1 revolution = πD
= π × 23 in
= 72.26 in
So, the distance moved in 1 revolution is 72.26 in
The number of revolutions in 10,000 miles is 8768337 revolutions
Since we require the number of revolutions in 10,000 miles, we convert this to inches.
So, 10000 miles × 5280 ft/mile × 12 in/1 ft = 633600000 in
Since 1 revolution = 72.26 in, the number of revolution in 633600000 in = 633600000 in ÷ 72.26 in/rev
= 8768336.56
≅ 8768337 revolutions
So, the number of revolutions in 10,000 miles is 8768337 revolutions
