The distance traveled is given by:
Where,
R: bicycle wheel radio
α: central angle
The angle for a revolution is:
Therefore, substituting values we have:
Clearing the radio we have:
Then, the diameter is given by:
Answer:
the diameter of the wheel is:
The circumference of a bicycle wheel traveling 30π inches in a revolution is equivalent to 30π. Using the circumference formula of a circle, C = πd, where C is the circumference and d is the diameter, we find that the diameter of the wheel is 30 inches.
The question is asking for the diameter of the bicycle wheel which travels 30π inches for each revolution. In other words, the distance that it travels in one full revolution is equivalent to the circumference of the wheel. The formula of the circumference of a circle (or wheel in this case) is C = πd, where C is the circumference and d is the diameter.
So if we plug our values into the formula, we get 30π = πd. Solving this equation for d (diameter), we simply divide each side by π. The π on the right side cancels out and on the left side the π in 30π also cancels out. The diameter of the wheel is therefore 30 inches.

The sentence is about the capacity of an auditorium, stating how many people it can hold. If you're asking for a translation into a different language, it would depend on the specific language.
The sentence 'The auditorium can hold a maximum 150 people.' is an English sentence stating the capacity of an auditorium - the maximum number of people it can safely accommodate. In terms of translation, if you meant translating to another language, the translation would vary based on the language. For example, in Spanish, it would be 'El auditorio puede albergar un máximo de 150 personas.'

2x^2 +3x
Answer:
Step-by-step explanation:
Real life = 8m = 8000mm
Drawing = 4mm
we can take the ratio of the two values (but be sure that they both have the same units, this is why it is necessary to convert 8m to 8000mm OR you can convert 4mm to its value in meters)
we can also write this as:
so the drawing's scale factor is:
This means that if length of the living room in the drawing is multiplied by 2000 it will be of the same length as the living room in real life.
