Ответ:
45 cm
Step-by-step 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
