Question

Jake draws a sketch of a compact disc of a diameter 4.8 inches

What is the circumference of the disc? round your answer to the nearest hundreth

Answer 1

To find the circumference of a circle, we use the formula:

\[
C = \pi d
\]

where \(C\) is the circumference and \(d\) is the diameter. Given that the diameter is 4.8 inches, we can substitute this value into the formula:

\[
C = \pi \times 4.8
\]

Using an approximation for \(\pi \approx 3.14\):

\[
C \approx 3.14 \times 4.8
\]

Calculating this:

\[
C \approx 15.072
\]

Now, rounding to the nearest hundredth:

\[
C \approx 15.07 \text{ inches}
\]

Therefore, the circumference of the disc is approximately **15.07 inches**.
