S side of column = C bottom H r = 25.12 divided by 3.14 divided by 2 = 4 (square centimeters)

=25.12*20

=502.4 ( Square centimeters)

S base = πr square

=3.14*4 squared

=50.24 (square centimeters) 50.24*2+502.4=602.88 (square centimeters) cm)

I don’t know if that’s the case, so I just do this and there’s hope again! ! !
