Question

what is the circumference of a circle with a diameter of 7 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 when the diameter \( d \) is known is \( C=\pi d \).

Step2: Substitute the given values

We are given that \( d = 7 \) units and \( \pi=3.14 \). Substituting these values into the formula, we get \( C = 3.14\times7 \).

Step3: Calculate the product

Calculating \( 3.14\times7 \), we have \( 3.14\times7 = 21.98 \).

Answer:

The circumference of the circle is \( 21.98 \) units.
