Question

diameter of a circle is 6.5 centimeters (cm). find the circumference of the circle in cm. leave the answer in terms of π.

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter into the formula

We are given that the diameter \( d = 6.5 \) cm. Substituting this value into the formula \( C=\pi d \), we get \( C = \pi\times6.5 \).
Simplifying, we can write \( 6.5\pi \) (or \( \frac{13}{2}\pi \) if we convert 6.5 to a fraction, but 6.5π is also correct).

Answer:

\( 6.5\pi \) (or \( \frac{13}{2}\pi \))
