Two cylinderical cans have same bases of diameter 21 cm. If one of them is 12 cm high and the other is 18 cm then, find the ratio of their volumes.
~> Ratio of the volumes of the two cylinder.
- Diameter of the two cylinders = 21 cm
- Height
- Height
☞✧Volume of the Cylinder ✧
In this case , by comparing the two volumes of the given cylinder we can find the ratio of there volumes......
By comparing the two volumes, we get
Radius and pie are equal in both the cases..
Hence , the ratio of volumes of the two cylinders is 2:3.......
- Surface area of square =
- lateral surface area of square =
- Surface area of rectangle =
- lateral surface area of rectangle =

∵ Radius and pie are equal in both the cases..
Hence , the ratio of volumes of the two cylinders is 2:3.......
Surface area of square = 6a^{2}6a
lateral surface area of square = 4a^{2}4a
Surface area of rectangle = 2(lb + lh + bh)2(lb+lh+bh)
lateral surface area of rectangle = 2h(l + b)2h(l+b)
