To find out how far a wheel travels after a certain number of revolutions, you first need to calculate the circumference of the wheel. The circumference \( C \) of a circle is given by the formula:

\[
C = \pi \times d
\]

where \( d \) is the diameter of the circle.

Given that the diameter of the wheel is 14 inches, we can calculate the circumference:

\[
C = \pi \times 14 \approx 3.14 \times 14 \approx 43.96 \text{ inches}
\]

Now, to find the distance traveled after 2 revolutions, you multiply the circumference by the number of revolutions:

\[
\text{Distance} = C \times \text{Number of Revolutions}
\]
\[
\text{Distance} = 43.96 \text{ inches} \times 2 \approx 87.92 \text{ inches}
\]

Thus, after 2 revolutions, the wheel travels approximately **87.92 inches**.
