Question

write all the formulas of cylinder and cone volume and all areas​

Answer 1

Answer:

$hello$

Step-by-step explanation:

1. CYLINDER

• The volume of a cylinder = Area of the base × Height of the cylinder = πr²h

• Lateral Surface Area = Perimeter of base × height = 2πrh = πdh

• Total Surface Area = Lateral Surface Area + Area of bases = 2πrh + 2πr² = 2πr (h+r)

• Volume of Hollow Cylinder = Vol of External Cylinder – Vol of Internal Cylinder = πR²h – πr²h = π (R² – r²) h

• Lateral Surface (hollow cylinder) = External Surface Area + Internal Surface Area = 2πRh + 2πrh = 2π(R+r)h

• Total Surface Area (cylinder) = Lateral Area = Area of bases = 2π(R+r)h + 2π (R² – r²) h

2.CONE

• Volume of a cone = 1313 area of base × height = 1313 πr²h

• Lateral Surface = 1212 radius × arc length = 1212 l × 2πr = πrl

• where l = slant height = √(r² + h²)

• Total Surface Area = lateral surface area + Area of base = πrl + πr²
