Question

the diameter of a circle measures 26 cm. what is the circumference of the circle? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given values

We are given that \( d = 26\) cm and \( \pi=3.14 \). Substituting these values into the formula, we get \( C = 3.14\times26 \).

Step3: Calculate the product

\( 3.14\times26 = 81.64 \). The unit for circumference is the same as the unit for the diameter, which is centimeters.

Answer:

\( 81.64 \) cm
