A vehicle travels 125.7 feet while its wheels revolve 16 times. find the diameter of the wheels to the nearest inch. d = inches.

Divide the total distance by the number of turns to find how far it traveled in one turn, this would give you the circumference of the tire:

125.7 / 16 = 7.85625 feet in one turn.

To find the diameter of a circle divide the circumference by PI:

7.85625 / PI (3.14) = 2.5 feet

1 foot equals 12 inches, multiply total feet by 12 to get inches:

2.5 x 12 = 30 inch diameter.
