To determine the circumference of a tire rim with a given diameter, we will use the formula for the circumference of a circle, which is:
[tex]\[ C = \pi \times d \][/tex]
where:
- [tex]\( C \)[/tex] represents the circumference,
- [tex]\( \pi \)[/tex] (pi) is a constant approximately equal to [tex]\( 3.14 \)[/tex],
- [tex]\( d \)[/tex] is the diameter of the circle.
Given that the diameter [tex]\( d \)[/tex] of the tire rim is [tex]\( 15 \)[/tex] inches, we substitute the values into the formula:
[tex]\[ C = 3.14 \times 15 \][/tex]
Multiplying these values:
[tex]\[ C = 47.1 \][/tex]
Therefore, the circumference of the tire rim is:
[tex]\[ 47.1 \, \text{inches} \][/tex]
So the correct answer is [tex]\( 47.1 \)[/tex] inches.
