Step-by-step explanation:

radius of cylinder =12

height =15

total surface area of cylinder =pie(r)(r+h)

pie(12)(12+15)

=22/7 (27)

=22/7(324)

plat form of cylinder is in circle shape

therefore, area of circle=pie(r)square

TSA of cylinder -area of platform

=22/7(324)-22/7(12x12)

=324-144

=180 ms

,the cost of painting for m square=25

180x25

=4500rs
