Formula
V=πr^2h

ORIGINS

• Circle base so use pi
• Squared radius for both bases
• Multiplied by the height
• To find the volume or space in between

REFLECTION

• What did you just see?
• How does this relate to geometry?
• What component of the object was lost?

INFORMATION

• The candle is 50cm tall
• 5cm of wax melts in a minute
• The radius of the candle is 35cm

THE QUESTION

• How long would it take
• For the candle to melt
• If it was lit and allowed
• To melt continuously?

PLUG IT IN

• V=πr^2h
• V=π(35^2)(50)
• V=π(1225)(50)
• V=π(61250)
• V=π(192325)^cm

FIND THE DIFFERENCE

• 60x5=300cm melted an hour
• 192325/300=641.1
• 641.1hours to melt
