Perimeter of base = 88

2πr = 88

r = 88/2π

r = 7cm

Volume = 1/3 πr^2

= 1/3 × 22/7 × 7 × 7

= 154/3

=51.33cm^3

l = h^2 + r^2

l = 48^2 + 7^2

l = 2304 + 49

l = 2353

l = 48.50cm

CSA = πrl

= 22/7 × 7 × 48.50

= 22×48.50

= 1067cm^2

TSA = πr(l+r)

= 22/7 × 7 ( 48.50 + 7 )

= 22 ( 55.50 )

=1221 cm^2
