A cylinder has a radius of 7 cm and a height of 3 cm. What is the total surface area of this cylinder?

Explanation

Given radius (r) = 7 cm and height (h) = 3 cm, the total surface area of a cylinder is calculated using the formula 2πr(h + r). Substituting the values: 2 × (22/7) × 7 × (3 + 7) = 2 × (22/7) × 7 × 10 = 440 square centimeters.
