Question

The circumference of a circle is 207 ft. Find its diameter, in feet.

Answer 1

SOLUTION

Given the question, the following are the solution steps to answer the question.

STEP 1: Write the given terms

$\begin{gathered} Circumference=207ft \\ diameter=? \end{gathered}$

STEP 2: Write the formula for calculatin the cirncumference of a circle

$\begin{gathered} Circumference=2\pi r=\pi d \\ Where\text{ d is the diameter} \end{gathered}$

STEP 3: Find the diameter

$\begin{gathered} Circumference=\pi\times d=207 \\ Divide\text{ both sides by pi} \\ d=\frac{207}{\pi}=65.89014644 \\ d\approx65.89ft \end{gathered}$

Hence, the diameter of the given circle is approximtely t65.89ft o two decimal places.
