Hey mate mark it as brainliest

Step-by-step explanation:

radius = 10.5 cm

height = 14 cm

inner total area = inner curved surface area  + base area

             = 2πrh + πr²

               = 2×(22/7)×14×10.5 + (22/7)×10.5²

               = 1270.5 cm²

rate = ₹10 per cm²

cost = 1270.5×10 = ₹12705
