Answer:

45 centimeters.

Explanation:

So first find the circumference of the wheel. If it travels 35.325 meters in 25 revolutions, one revolution should travel 1.413 meters.

The circumference is 1.413 meters.

The circumference is also Dπ


D=(1.413)/(3.14)

D ≈ 0.45

0.45 meters = 45 centimeters.

Answer:

45 cm

Explanation:

The distance the wheel travels in 1 revolution is the circumference

C = pi *d

25 revolutions is 25 * C = 25 * pi *d

This is 35.325 meters

35.325 = 25 * pi *d

Using 3.14 for pi

35.325 = 25*3.14*d

35.325 =78.5d

Divide each side by 78.5

35.325/78.5 = d

.449936306 = d

The diameter is .449936306 meter

Changing to cm by multiplying by 100

44.9936306 cm

Rounding to the nearest cm

45 cm
