Please help me understand this.
A tire on a miniature car has a diameter of 1.468 inches. The circumference of a tire for a full size car is 65.97 inches.
To the nearest tenth, what is the circumference of the miniature tire? (C = πd)
Yes, the incorrect value of pi might have led to an incorrect answer. It's important to use the correct value of pi (or an appropriate approximation) when calculating the circumference or area of a circle. Using an accurate value for pi will ensure more precise and reliable results in your calculations. If you have any more questions or need further clarification, feel free to ask!
Thank you so much for your kind words! I'm glad I could assist you. If you have any more questions in the future, don't hesitate to ask. I'm here to help! ⭐⭐⭐⭐⭐
To find the circumference of the miniature tire, we need to use the formula C = πd, where C represents the circumference and d represents the diameter.
Given that the diameter of the miniature tire is 1.468 inches, we can substitute this value into the formula:
C = π * 1.468
Using an approximation of π as 3.14, we can calculate the circumference:
C = 3.14 * 1.468 = 4.60352
To round to the nearest tenth, the value becomes:
C ≈ 4.6 inches
Therefore, the circumference of the miniature tire, rounded to the nearest tenth, is 4.6 inches.
I'm still not understanding could you explain a little easier??
Sure, let me explain in simpler terms.
The circumference of a circle is the distance around the outside of the circle. In this case, we need to find the circumference of a miniature tire.
To find the circumference, we can use the formula C = πd, where C represents the circumference and d represents the diameter of the tire.
The diameter of the miniature tire is given as 1.468 inches. We can substitute this value into the formula:
C = π * 1.468
Now, the value of π is approximately 3.14. So, we can calculate the circumference as follows:
C = 3.14 * 1.468 = 4.60352
To round the answer to the nearest tenth, we look at the digit in the first decimal place. In this case, that digit is a 6, which is closer to 5 than 6, so we round down.
Therefore, the circumference of the miniature tire, rounded to the nearest tenth, is approximately 4.6 inches.
Now how do I round the 4.6 to the nearest tenth?
I apologize for the confusion.
To round 4.6 to the nearest tenth, you need to look at the first decimal place, which is 6 in this case.
Since 6 is greater than or equal to 5, you need to round the number up. Therefore, the rounded value of 4.6 to the nearest tenth is 4.7.
Okay, last question.
To the nearest tenth, how many times greater is the circumference of the full-size car's tire when compared to the circumference of the miniature car's tire?
To find out how many times greater the circumference of the full-size car's tire is compared to the circumference of the miniature car's tire, we can divide the circumference of the full-size car's tire by the circumference of the miniature car's tire.
Given:
Circumference of full-size car's tire = 65.97 inches
Circumference of miniature car's tire = 4.6 inches (rounded)
Now we can calculate the ratio:
Ratio = Circumference of full-size car's tire / Circumference of miniature car's tire
Ratio = 65.97 / 4.6
Ratio ≈ 14.339
To the nearest tenth, the ratio is approximately 14.3.
Therefore, the circumference of the full-size car's tire is approximately 14.3 times greater than the circumference of the miniature car's tire.
