slant height,l =√(2.5)square+ (6)square=6.5cm
the area to be painted green=CSA of cone + base area of cone – base area of cylinder
= πrl + πr square – πr' square
= π ( 2.5 × 6.5) + 6.25 – 2.25
= π × 20.25 cm square
= 63.585 cm square
area to be painted red = CSA of cylinder + area of one base of cylinder
= 2πrh + πr square
= πr(2h + r )
= ( 3.14 × 1.5 ) ( 2× 20 + 1.5 ) cm square
= 4.71 × 41.5 cm square
= 195.465 cm square
