Total Surface Area = Area of the top circle + Area of the bottom + the lateral surface area.

Radius = Diameter ÷ 2 = 7.6 ÷ 2 = 3.8 cm

Area of the top circle = πr² = π (3.8)² = 45.36 cm²

Area of the bottom circle = Area of the top circle = 45.36 cm²

Area of the lateral surface = 2πrh = 2π(3.8)(7.2) = 171.91 cm²

Total Surface area = 45.36 + 45.36 + 171.91 = 262.63 cm²

Answer: 262.63 cm²
