If the wheel radius of a bicycle is 0.33 meters, the wheel rolls 100 cycles, and the bicycle advances () meters?

If the wheel radius of a bicycle is 0.33 meters, the wheel rolls 100 cycles, and the bicycle advances () meters?

Diameter 2 × 0.33 = 0.66M
Perimeter 3.14 × 0.66 = 2.0724m
The bicycle advanced 2.0724 × 100 = 207.24m

A. B two bicycles, assuming that the tire diameter of car a is 80 cm and that of car B is 60 cm
It is known that the number of turns per minute of car a is 3 / 4 of that of car B,
There is a reward for a good answer.

Because the outside diameter of a car tire is 80 cm, the outside diameter of B car tire is 60 cm
So the circumference of the two tires is 80 Pai and 60 Pai cm
Because the number of turns per minute of car a is 3 / 4 of that of car B,
So the distance ratio of two cars per minute = (80 pies * 3 / 4): 60 pies = 1:1
Speed = distance / time
So it's just as fast

The diameter of the bicycle wheel is 64. What's the speed of 150 turns per hour

64×3.14=200.96
200.96×150=30144
As for your speed per hour, it's a question mark "?", so I can't answer it. If you ask the question of how much you turn, then I'll answer the above!

Why are big wheels so different from small ones?
Give everybody brush cent, can
Do you think he is responsible for what he said? I pour cold water on it? I'm just giving you a space for discussion. People like you are not worth it.

As for going upstairs, do you think he is responsible for saying this? Going upstairs, he said: you need to solve the problem when you come here. This sentence is right, but "I have to doubt if you are pouring cold water on us." it is obvious that he is venting for himself! The landlord also said that he wants to discuss with the big family! Going upstairs misunderstood the meaning, but venting for himself. Do you think he is doing this right?
Big wheels and small wheels + me, I'll give you the answer
