Answer 2

Answer:

Hey friend,

Here is the answer you are searching for,

Given,

Diameter = 10.5 cm

=> Radius = 10.5/2 cm

Area of sphere = 4πr²

=> Area of hemisphere = 1/2(4πr²) = 2πr²

Therefore,

Area = 2 × 22/7 × 10.5/2 × 10.5/2

= 22/7 × 105/10 × 105/20

= 22/7 × 21/2 × 21/4

= 11 × 3 × 21/4

= 173.25 cm²

Therefore,

Required cost =173.25/100 × 16

= ₹27.72

HOPE IT HELPS YOU.
