Presentation Transcript

  1. Cones

  2. Examples of a cone • Ice cream cone • Party hats • Traffic cones • Funnels

  3. Volume formula of a cone • V= volume • = pi • R= radius • H= height

  4. Surface area formula of a cone • SA= rs+ • SA= Surface area • = pi • S= slant height

  5. Volume of a cone problem • You are shipping party hats to Party City. The hats have a height of 10 in, a radius of 5, and a side length of 8. How much packing will you need so they don’t get crushed?

  6. Volume of a cone (cont.) • v=125*10*3.14*1/3 = 1308.3

  7. Surface area of a cone problem • An ice cream cone factory is making ice cream cones. The cones must have a radius of 3in, and a slanted height of 2in. How much cone surface area will there be for each cone?

  8. Surface area of a cone (cont.) • SA= rs+ • SA= + • SA= 3.14*3*2+3.14*3*3=
