Question

what is the circumference of a circle with a diameter of 25 units? use π = 3.14 and round your answer to the nearest hundredth.

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 \( d = 25 \) units and \( \pi = 3.14 \). Substituting these into the formula, we get \( C = 3.14\times25 \).

Step3: Calculate the product

\( 3.14\times25 = 78.5 \). Since we need to round to the nearest hundredth, and \( 78.5 \) is already to the tenths place, we can write it as \( 78.50 \) (or just \( 78.5 \) as the hundredth place is zero and doesn't change the value when rounded).

Answer:

78.50 (or 78.5)
