Answer 1

To find the circumference \( C \) of a circle using the formula \( C = \pi d \), where \( d \) is the diameter, you can plug in the given diameter and the value of \( \pi \).

Given:

• Diameter \( d = 3.75 \) feet
• \( \pi \approx 3.14 \)

Now, substitute these values into the formula:

\[ C = \pi d = 3.14 \times 3.75 \]

Calculating this:

\[ C = 3.14 \times 3.75 = 11.775 \]

Now, round to two decimal places:

Thus, rounding \( 11.775 \) gives us \( 11.78 \).

So the correct response is:

11.78 ft
