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.
PLEASE MARK AS BRAINLIEST...
