How do you solve this problem?
use the definition of pi
C = pi d
So, in one revolution, the tire moves a length equal to the circumference of the tire.
After 15 revolutions, the distance is
pi * d * 15 = 120 pi inches = 10 pi ft = 31.4 ft
C = pi d
So, in one revolution, the tire moves a length equal to the circumference of the tire.
After 15 revolutions, the distance is
pi * d * 15 = 120 pi inches = 10 pi ft = 31.4 ft
Use to formula C=2(PI)r
C=2(3.14)8
C=6.28(8)
C=50.24
Then multiply the circumference by 15.
50.24x15=753.6in
The because since your answer is in inches you must now convert it to feet.
753.6in= 62.8 feet
Therefore, your answer is 62.8 ft.
Hope this helped!
