If the height of a cylinder is increased by 3 cm, the height of the cylinder is equal to the circumference of the bottom surface, and the area is increased by 94.2 square cm. The volume of the original cylinder is calculated

If the height of a cylinder is increased by 3 cm, the height of the cylinder is equal to the circumference of the bottom surface, and the area is increased by 94.2 square cm. The volume of the original cylinder is calculated

Bottom perimeter: 94.2 △ 3 = 31.4cm
Bottom radius: 31.4 △ 3.14 △ 2 = 5cm
Original height: 31.4-3 = 28.4cm
Original volume: 3.14 × 5 × 5 × 28.4 = 2229.4 cubic centimeter
