To find the circumference of a circle, you can use the formula:
\[
C = \pi \times d
\]
where \( C \) is the circumference and \( d \) is the diameter. Given that the diameter of the compact disc is 4.8 inches, we can substitute this value into the formula.
\[
C = \pi \times 4.8
\]
Using \( \pi \approx 3.14159 \):
\[
C \approx 3.14159 \times 4.8 \approx 15.079
\]
Rounding to the nearest hundredth:
\[
C \approx 15.08
\]
So, the circumference of the disc is **15.08**.
