1. To find the lateral area of the cone, use the formula: π * radius * slant height.
=> 3.14 * 7 * 13
=> 286.38, which when rounded to the nearest tenth is 286.4, which is not in the options provided. I assume there might be a typo in the question or the options since none of them match the correct answer.
2. To find the surface area of a square pyramid, first find the slant height using the Pythagorean theorem:
=> √(height^2 + (base_length / 2)^2)
=> √(16^2 + (24 / 2)^2)
=> √(256 + 144)
=> √400
=> 20 cm
The area of the base is base_length * base_length.
=> 24 * 24
=> 576 cm2
The area of the 4 triangular faces is 0.5 * base_length * slant_height for each triangular face, multiplied by 4.
=> 4 * (0.5 * 24 * 20)
=> 960 cm2
Now add the area of the base and the area of the triangular faces:
=> 576 + 960
=> 1536 cm2
Answer: B. 1536 cm2
3. Please provide the diagram or dimensions of the cylinder as the question states.
4. Please provide the diagram or dimensions of the cylinder as the question states.
5. To find the volume of a rectangular prism, simply multiply its dimensions.
=> length * width * height
=> 5 * 7 * 3
=> 105 mm3
Answer: B. 105 mm3
6. There are no dimensions provided for the pyramid. Please provide dimensions or context for the question.
7. To find the volume of a square pyramid, use the formula: (1/3) * base_area * height.
=> (1/3) * 9 * 9 * 4
=> 108 cm3
Answer: B. 108 cm3
8. No dimensions or context were provided for this cone question. Please provide more information.
9. To find the volume of a cone, use the formula: (1/3) * π * radius^2 * height.
=> (1/3) * 3.14 * 10^2 * 6
=> (1/3) * 3.14 * 100 * 6
=> 628 mm3
Answer: A. 628 mm3
