Answer 1

Hello !
___________________________________________________________
here 
Radius (r) =   5 cm 
height  (h) = 10 cm 
TSA          =  2πr(h+r) 
TSA          = 2 x 3.14 x 5 ( 10 + 5) 
                 = 31.4(15) = 471 cm²
____________________________________________________________
In terms of π
TSA = 2 π r (h + r ) 
        = 10 π (15 ) 
        = 150π

Answer 2

Given,

Radius of a solid cylinder (r) = 5 cm

Height (h) = 10 cm

Hence,

Total surface area = 2πrh + 2πr²

= 2rπ(h + r)

= 2π × 5(10 + 5)

= π × 10 × 15

= 150π cm²
