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
Options must have ommitted the "π"
I think this is correct. I’m not for sure but I did a lot of work. You put g(2) in linear standard which is practically alphabetical order in which numbers go before letters. You do this for both question. So both go to 2(g) and 5(g). Then you multiply g by the number and get 2(2) and 5(5). Then multiply the two numbers and get 2(2)=4 and 5(5)=25.
