Question

what is the circumference of a circle with a diameter of 4.5 miles? estimate the circu the hundredths place using 3.14 for π. (1 point)
14.2 miles
63.59 miles
14.13 miles
7.07 miles

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference \( C \) of a circle is \( C=\pi d \), where \( d \) is the diameter.

Step2: Substitute the given values

We know that \( d = 4.5 \) miles and \( \pi=3.14 \). Substitute these values into the formula: \( C = 3.14\times4.5 \)

Step3: Calculate the product

\( 3.14\times4.5=(3 + 0.14)\times4.5=3\times4.5+0.14\times4.5 = 13.5+0.63=14.13 \)

Answer:

14.13 miles (corresponding to the option "14.13 miles")
