Q1.what's the formula to find tsa , LSA and volume of cylinder?
Answers
Explanation:
➞ Total surface area or tsa is the total area occupy by solid object including its top and bases surface.
Formula for finding surface area of cylinder:
➞Surface area of cylinder= Curved surface area + area of its 2 circular bases
➞Surface area of cylinder= 2πrh+πr²+πr²
➞Surface area of Cyclinder= 2πrh+2πr²
➞Surface area of Cyclinder= 2πr(r+h)
-----------------------------------------------------------
Lateral or curved surface area (csa)
➞Lateral surface area is the total area occupy by a solid object from its bottom to top surface edges only.
Formula for finding lateral surface area
➞Lateral surface area of Cyclinder=2πrh
Where ,h is the height ,r is the radius and π some constant value.
-----------------------------------------------------------
Volume of cylinder:
➞Volume is the total capacity a solid object can hold in it.
Volume of cylinder= Base area × height
Base area = πr²
height is 'h'
So,volume of cylinder= πr²h
