Explanation:
The total surface area of the cylinder can be calculated using the following formula: Surface Area = 2πrh + 2πr². Substitute 18 cm for the height (h) and 24 cm for the radius (r): Surface Area = 2π(18 cm)(24 cm) + 2π(24 cm)² = 864π cm² ≈ 2735.9 cm². Therefore, the total surface area of the cylinder is approximately 2735.9 cm² to 1 decimal place.
