Answer:
Step-by-step explanation:
Since we know the total surface area of a prism is equal to the sum of all its faces, i.e., the floor, walls, and roof of a prism. Therefore, the surface area of a prism formula is given as: Total surface area of a prism = 2 x area of the base + perimeter of the base x Height.
mark me brill please
You take the base ten block and keep putting them in 8 groups then you will get the answer 98 hope I helped
Radius of the inner circle = 13.2 ÷ 2 = 6.6 mm
Area of the inner circle = π (6.6)² = 43.45π mm²
Radius of the larger circle = 6.6 + 4.4 = 11mm
Area of the larger cicle = π(11)² = 121π mm²
Area of the washer = 121π - 43.45π = 243.3 mm²
Answer: 243.3 mm²
I feel like this would just be 108cm squared but I could be wrong...
Step-by-step explanation:
