Answer:
1.) A. Area
2.) C. Square area
3.) SA = πr2 + πrl
Step-by-step explanation:
1.) Area of any prism is the sum of areas of its lateral sides and bases- the sum of areas of all polygons that that prism is bound with. If you want to calculate it, first you’d find all separate areas and then just sum them. Volume of prisms is equal to the product of the area of the base and height of that prism.
2.) Square area is the product of the perimeter of the base and the height of a prism.
3.)The total surface area of a cone is the combination of the curved surface as well as the base area of a cone. The formula to calculate the total surface area of the cone is: TSA of cone = πr 2 + πrl = πr (l+r) square units.
