Question

A comical flask of radius 7 cm and height 9 cm is full of water. It the water is prouded into four cylindrical flasks of radius 7/2 cm, height 'h'. Each such that all the cylindrical flasks are filled completely. Find the curved surface area of a cylindrical ​

Answer 1

Answer:

66 cm².

main thing is volume of cylinder×4=Volume of cone.

Answer 2

Answer:

The curved surface area of the cylindrical flask is 66 cm²

Explanation:

The curved floor location of a cylinder (CSA) is described because the location of the curved floor of any given cylinder having a base radius 'r', and height 'h', It is likewise termed as Lateral Surface Area (LSA). The formulation for a curved location or lateral location is given by: CSA or LSA = 2π × r × h Square units.

=1/3 x 22/7 x 7 x 7 x 9 = 4 x 22/7 x 7/2 x h

⇒ h=3

c s a of cylinder = 2π × r × h Square units.

⇒ 2 x 22/7 x 3

⇒ 66 cm²

The curved surface area of the cylindrical flask is 66 cm²
