Answers
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:
Final answer:
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.
Explanation:
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.

Answer: the number of cephalopods in her seashells collection is 26.
Step-by-step explanation:
Maria has a collection of 64 seashells consisting of three types bivalves,gastropods,and cephalopods. If 1/4 of her collection are bivalves, it means that the number of bivalves that she has is
1/4 × 64 = 14
If 3/8 of her collection are gastropods, it means that the number of gastropods in her collection is
3/8 × 64 = 24
Therefore, the number of cephalopods in her seashells collection is
64 - (14 + 24) = 26
