Answer 2

$\huge\boxed{\fcolorbox{blue}{orange}{Solution:}}$

Dimensions of the cylinder Piller is

Diameter = d = 1 m

Radius ( r )= d / 2 = 1 / 2 m

Height = h = 4.2 m

Curved surface area of the cylinder

C.S.A = 2πrh

= 2 × 22 / 7 × 1 / 2 × 4.2

= 13.2 square meters

Cost of white washing the CSA of

Piller per square meter = Rs 15

Cost of white washing the 13.2m Piller

= 13.2 × 15

= Rs 198
