Question

find the circumference of a circle whose diameter is 25 in. use 3.14 for $pi$. enter a number.

Explanation:

Step1: Recall the formula

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

Step2: Substitute the values

Given $d = 25$ in and $\pi=3.14$, we have $C=3.14\times25$.

Step3: Calculate the result

$3.14\times25 = 78.5$ in.

Answer:

$78.5$
