TSA= {2πr^2} + 2πrh
=(2*3.14*10*10)+2*3.14*10*30
=2*314. + 6*314
=2512 cm^2
=(2*3.14*10*10)+2*3.14*10*30
=2*314. + 6*314
=2512 cm^2

diameter = 20 cm
radius , r = 10 cm
height , h = 30 cm
Total surface area of cylinder ,
A = 2 π r ( h + r )
A =2 π 10 ( 10 + 30 ) = 20 π * 40
A = 800 * 3. 14
A = 2512 cm²
radius , r = 10 cm
height , h = 30 cm
Total surface area of cylinder ,
A = 2 π r ( h + r )
A =2 π 10 ( 10 + 30 ) = 20 π * 40
A = 800 * 3. 14
A = 2512 cm²
