Question

cylendrical object from day to day life and find csa and tsa of the object

Answer 1

Answer:

A cylinder is a three-dimensional solid that consists of two parallel circular bases connected to each other with the help of a curved surface. Cylinder, the word has been derived from the Latin word ‘cylindrus’ and the Greek word ‘kylindros’. The line passing from the centre or joining the centres of two circular bases of a cylinder is called the axis. The distance between the circular bases of the cylinder is the perpendicular distance and is represented as height or by the letter ‘h’. The distance between the centre of the base of a cylinder and the outer boundary of the cylinder is the radius of the cylinder, which is represented by ‘r’.

Answer 2

Answer:

so lets start

now let's take gas cylinder

radius=7m height= 14m

csa =2πrh

2×22/7×7×14=616m^2

tsa=2πr(r+h)

=2×22/7×7(7+14)

=921m^2
