volume of vessel = πr^2h + 2/3πr^3
= πr^2(h+2/3r)
= 22/7 × 3.5 × 3.5(14/3+2/3×3.5)
= 22×0.5×3.5(14/3+7/3)
= 11×3.5(21/3)
= 38.5×7
= 269.5m^3
surface area = 2πrh+2πr^2
=2πr(h+r)
= 2×22/7×3.5(14/3+3.5)
= 44×0.5(24.5/3)
= 22 × 24.5/3
= 539/3
=179.66m^2
= πr^2(h+2/3r)
= 22/7 × 3.5 × 3.5(14/3+2/3×3.5)

= 11×3.5(21/3)

surface area = 2πrh+2πr^2

= 44×0.5(24.5/3)
= 22 × 24.5/3
