Answer:
5.5+106 square inches
Step-by-step explanation:
The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.
To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =
π(6²-5²)/2= 11π/2
=5.5π square inches
We add area of the semi circle to area of the 3 rectangles from the diagram:
2×1×48×10×1=106 square inches
The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area
Total area =5.5π +106 square inches

Answer:
-1 1/2 and -1 3/4 on the number line.
Step-by-step explanation:
First you find -1 on the number line. Then you add 1/2 which is also 2/4. You find it by going two places from -1 to the right.
Then you do the same for -1 3/4. You start at -1 and move 3 places to the right.
