Answer:
The cylindrical tin is (much!) larger.
The difference between their capacities is 1477.1 cm³
Step-by-step explanation:
Volume of square base tin
= area of base × height
= 8 cm × 8 cm × 13 cm
= 832 cm³
Volume of cylindrical tin
= area of base × height
= π × 7 cm × 7 cm × 15 cm
= 735 π cm³
≈ 2309.1 cm³
The cylindrical tin is (much!) larger.
The difference between their capacities is
2309.1 cm³ - 832 cm³ = 1477.1 cm³

how you have done area of square base tin
Area = pi times radius squared. Here the radius is 7 cm, so the area is pi times 7 cm times 7 cm
