Question

find the circumference of the circle. use 3.14 for π. 7 in. the circumference of the circle is about inches.

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: Identify the diameter

From the diagram, the diameter \( d = 7 \) inches.

Step3: Substitute values into the formula

We are given \( \pi = 3.14 \) and \( d = 7 \). So, \( C=3.14\times7 \).

Step4: Calculate the product

\( 3.14\times7 = 21.98 \).

Answer:

21.98
