Question

1. mp use structure hans opens a circular window that is 3.5 feet across at its widest point. what is the circumference of the window to the nearest whole number? use 3.14 for $pi$.

Explanation:

Step1: Identify diameter of window

The widest point of a circle is its diameter, so $d = 3.5$ feet.

Step2: Recall circumference formula

The formula for circumference is $C = \pi d$.

Step3: Substitute values and calculate

Substitute $\pi = 3.14$ and $d = 3.5$:
$C = 3.14 \times 3.5 = 10.99$

Step4: Round to nearest whole number

$10.99$ rounds up to 11.

Answer:

11 feet
