?. A design is made from a wood panel in the shape of a regular decagon, whose side measures 11 feet and apothem measures 16.93 feet. Inside the regular decagon shape there is a hole that is also shaped as a regular decagon, but whose side measures 2 feet and apothem measures 3.08 feet.What is the area of the panel of wood without the hole? Round your answer to the nearest hundredth.
Q. ?. A design is made from a wood panel in the shape of a regular decagon, whose side measures 11 feet and apothem measures 16.93 feet. Inside the regular decagon shape there is a hole that is also shaped as a regular decagon, but whose side measures 2 feet and apothem measures 3.08 feet.What is the area of the panel of wood without the hole? Round your answer to the nearest hundredth.
Calculate Perimeter of Larger Decagon: To find the area of the larger decagon, use the formula for the area of a regular polygon: Area=21×Perimeter×Apothem. First, calculate the perimeter of the larger decagon by multiplying the length of one side by the number of sides: Perimeter=11feet×10.
Calculate Area of Larger Decagon: Perimeter of the larger decagon = 11×10=110 feet.
Calculate Perimeter of Smaller Decagon: Now, calculate the area of the larger decagon using the apothem: Area=21×110 feet×16.93 feet.
Calculate Area of Smaller Decagon: Area of the larger decagon = (21)×110×16.93=930.65 square feet.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter = 2 feet×10.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter = 2 feet ×10. Perimeter of the smaller decagon = 2×10=20 feet.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter = 2 feet×10. Perimeter of the smaller decagon = 2×10=20 feet. Now, calculate the area of the smaller decagon using its apothem: Area = (1/2)×20 feet×3.08 feet.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter = 2 feet×10. Perimeter of the smaller decagon = 2×10=20 feet. Now, calculate the area of the smaller decagon using its apothem: Area = (1/2)×20 feet×3.08 feet. Area of the smaller decagon = (1/2)×20×3.08=30.8 square feet.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter = 2 feet×10. Perimeter of the smaller decagon = 2×10=20 feet. Now, calculate the area of the smaller decagon using its apothem: Area = (1/2)×20 feet×3.08 feet. Area of the smaller decagon = (1/2)×20×3.08=30.8 square feet. Finally, subtract the area of the smaller decagon from the area of the larger decagon to find the area of the wood panel without the hole: 930.65 square feet−30.8 square feet.
Find Area of Wood Panel: Next, calculate the perimeter of the smaller decagon (the hole) in the same way: Perimeter =2 feet×10. Perimeter of the smaller decagon =2×10=20 feet. Now, calculate the area of the smaller decagon using its apothem: Area =21×20 feet×3.08 feet. Area of the smaller decagon =21×20×3.08=30.8 square feet. Finally, subtract the area of the smaller decagon from the area of the larger decagon to find the area of the wood panel without the hole: 930.65 square feet−30.8 square feet. Area of the wood panel without the hole =930.65−30.8=899.85 square feet. Round this to the nearest hundredth.
