Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
Considering the 16 oz jar,
h = 7 inches
Diameter = 5 inches
Radius = diameter/2 = 5/2
r = 2.5 inches
Volume = 3.14 × 2.5² × 7 = 137.375 inches³
Considering the 29 oz jar,
h = 7.5 inches
Diameter = 5.25 inches
Radius = diameter/2 = 5.25/2
r = 2.625 inches
Volume = 3.14 × 2.625² × 7.5 = 162.27 inches³
1) If the cost is directly proportional to volume, then
If 137.375 inches³ cost $1.6
then 162.27 inches³ should cost
(162.27 × 1.6)/137.375 = $1.89
The price of the larger jar would be $1.89
2) If the cost is directly proportional to weight, then
If 16 oz cost $1.6, then
29 oz would cost
(29 × 1.6)/16 = $2.9
The price of the larger jar would be $2.9
