Maths - Volume of Solids

1. Pyramid

   • Volume
     • 1/3 x base area x height

2. Spheres

   • Volume
     • 4/3 x Pi x radius2
   • Curved Surface Area
     • 4Pi x radius2

3. Arcs and Sectors

   • Arc Length = Angle / 360 x Pi x Diameter
   • Area of Sector = Angle / 360 x Pi x Radius2

4. Cylinders

   • Volume
     • Pi x radius2 x height
   • Curved Surface Area
     • Pi x Diameter x Height
   • Total Surface Area
     • (2Pi x radius x height) + (2Pi x radius2)

5. Cones

   • Volume
     • 1/3 x Pi x radius2 x height
   • Curved Surface Area
