Question

tyron is making cookies. he uses a circular cookie cutter with a diameter of 4 cm. what is the circumference of each cookie? use 3.14 as an approximation of π. round to the nearest tenth.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter.

Step2: Substitute the given values

We know that \( d = 4 \) cm and \( \pi \approx 3.14 \). Substituting these values into the formula, we get \( C = 3.14 \times 4 \).

Step3: Calculate the result

\( 3.14 \times 4 = 12.56 \)

Answer:

The circumference of each cookie is \( 12.56 \) cm.
