Question

one of a trees rings has a diameter of 20 cm.

what is the circumference of the trees ring? use 3.14 for π.

c =
cm

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 \( d = 20 \) cm and \( \pi = 3.14 \). Substituting these values into the formula, we get \( C = 3.14 \times 20 \).

Step3: Calculate the result

\( 3.14 \times 20 = 62.8 \).

Answer:

62.8
