The fair price for a jar of jam that is 4 cm in diameter and 6 cm in height.

70[(2^2*6*pi/1.5^2*5*pi)] = $1.49 (rounded to the nearest cent)

D₁ and h₁ = 3cm and 5cm respectively ; C₁ = 70¢

D₂ and h₂ = 4cm and 6cm respectively ; C₂ = ??

C₂ = C₁( D₂² * h₂ ) / ( D₁² * h₁ )

C₂ = 70¢( (4cm)²(6cm) ) / ( (3cm)²(5cm) ) C₂ = 149¢

149 cents

Fair from what point? The amount of material needed to make the jar? The volume of the product in the car?

Volume V1= (π/4)(45) , Volume V2= (π/4)(96)

---> price of larger jar = (96/45) of 70c = 149 cents
