Answer:
Inner radius of the hemispherical bowl;r = 6 cm
Thickness of the bowl = 0.50 cm
So, outer radius of the bowl;R = 6 cm + 0.50 cm = 6.50 cm
So outer curved surface area of bowl = 2πR2 = 2×227×(6.50)2 = 265.571 cm22πR2 = 2×227×6.502 = 265.571 cm2
And volume of the bowl = 23πr3 = 23×227×63 = 452.571 cm3
