How to calculate the area of a circular cylinder with a diameter of 60 cm and a diameter of 40 cm and a height of 15 cm

How to calculate the area of a circular cylinder with a diameter of 60 cm and a diameter of 40 cm and a height of 15 cm

1. Circle area = π (D / 2) ^ 2, so the area of a circle with a diameter of 60 cm is
3.14 × (60 / 2) ^ 2 = 3.14 × 900 = 2826 square centimeter [1cm = 1cm]
2. Side area = perimeter of bottom multiplied by height, and perimeter of bottom is π D, so,
The diameter is 40 cm and the height is 15 cm
3.14 × 40 × 15 = 3.14 × 600 = 1884 square centimeter
