Here we will tin-plate the inside of the hemisphere So, We need to find the curved surface area of hemisphere
Radius of hemisphere = r = /2 = (10.5/2) cm = 5.25 cm
Curved surface area of the hemisphere = 22 = (2×22/7×5.25×5.25) cm2 = 173.25 cm2
Cost of tin-plating 100 cm2 = Rs 16
Cost of tin-plating 1 cm2 = Rs 1/100 × 16
Cost of tin-plating 173.25 cm2 = Rs 1/100 × 16 × 173.25 = Rs 27.72
∴ Cost of tin-plating the hemisphere is Rs 27.72
HOPE IT HELPS!!^_^
