Acarpenter is making a wooden window frame that has a width of 1 inch.
how much wood does the carpenter need to build the frame?
5.5 + 106 square inches
5.5 + 116 square inches
5.5 + 153 square inches
5.5 + 162 square inches

We have been given diagram of a wooden window. We are asked to find the amount of wood that carpenter needs to build the frame.

The amount of wood needed for the window frame will be equal to area of window frame.

We can see that upper part of window is semicircle. The area of the semicircle is half the area of the circle.

, where,

R = Outer radius,

r = Inner radius.

The area of lower part of frame will be area of 3 rectangles. 2 same rectangles with length 48 inches and width 1 inch. One rectangle with length 10 inches (12-2) and width 1 inch.

Therefore, option A is the correct choice.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
