What is the circumference of a circle with a diameter of 4.5 miles? Estimate the circumference to the hundredths place using 3.14 for π.
1. 63.59 miles
2. 7.07 miles
3. 14.2 miles
4. 14.13 miles
The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.
Given a diameter of 4.5 miles, we can substitute this value into the formula:
C = 3.14 x 4.5
C ≈ 14.13 miles
Therefore, the correct answer is option 4. 14.13 miles.
To find the circumference of a circle, you can use the formula:
Circumference = π * Diameter
Given the diameter of 4.5 miles, let's substitute the value into the formula:
Circumference = 3.14 * 4.5
Calculating this:
Circumference = 14.13 miles
Therefore, the estimate of the circumference of a circle with a diameter of 4.5 miles, rounded to the hundredths place, is 14.13 miles.
The correct answer is option 4: 14.13 miles.
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter.
In this case, the diameter is given as 4.5 miles. To find the circumference, you need to multiply the diameter by π.
Using the value of π as 3.14, multiply it by the diameter of 4.5 miles:
C = 3.14 * 4.5
C ≈ 14.13 miles
Therefore, the estimated circumference of the circle, rounded to the hundredths place, is 14.13 miles. So the correct answer is option 4.
