The diameter of the bottom surface of a cylinder is 10 cm, and the height is 15 cm? A increased by 150 square centimeters. B reduced by 150 square centimeters. C increased by 300 square centimeters.

The diameter of the bottom surface of a cylinder is 10 cm, and the height is 15 cm? A increased by 150 square centimeters. B reduced by 150 square centimeters. C increased by 300 square centimeters.

The surface area is increased by two sections, the length and width of which are the diameter of the bottom and the height of the cylinder
2 section area = 10 × 15 × 2 = 300 square centimeter
C increased by 300 square centimeters
