Answer 1

To find the circumference of a circle, you can use the formula:

\[
\text{Circumference} = \pi \times \text{diameter}
\]

Given that the diameter of the window is 15 centimeters and using 3.14 for \( \pi \):

\[
\text{Circumference} = 3.14 \times 15
\]

Now, calculate it:

\[
\text{Circumference} = 3.14 \times 15 = 47.1 \, \text{cm}
\]

So the circumference of the window is **47.1 cm**.
