If you lived in a hobbit house and had a round window that needed? trim, how much trim would be needed to go around a window wit
katen-ka-za [31]

Answer:

To find out how much trim you would need for the window, you would need to calculate the Circumference.

Step-by-step explanation:

<u>Circumference</u> is the length around a circle and is calculated using the following formula.

C = 2\pi r

In which C is the circumference and r is the radius. Since we already know the radius all we have to do is plug it into the equation and solve for C.

C = 2\pi (4.2)

C = 26.389 ft

<u>Answer:</u> The window has a Circumference of 26.389 feet so you would need that amount of trim to fit the area around the window.

Hope my answer would be a great help for you.
