thickness of hemispherical bowl =0.25 cm
inner radius of hemispherical bowl=5 cm
outer radius of hemispherical bowl = (5+0.25) cm
=5.25 cm
outer curved surface area of the bowl=2
=6.18*5.25*5.25
=6.18*27.5
=170.33

inner radius =5cm
thickness=0.25cm
so,outer radius=5+0.25
=5.25cm
outer c.s.a=2×pi×r^2
=2×3.14×5.25^2
=6.28×441/16
=173.0925cm^2
thickness=0.25cm
so,outer radius=5+0.25
=5.25cm
