  • I am assuming the picture is of a stained glass window in the shape of a semicircle.

Answer: 7.71 feet.

Step-by-step explanation: The formula for finding the circumference of a circle is [tex]\frac{1}{2}[/tex] π × d + d.

The diameter is 3 feet. Substitute this into the equation:

[tex]\frac{1}{2}[/tex] π × 3 + 3.

Solve -

3.14 × 3 = 9.42

[tex]\frac{1}{2}[/tex] of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~
