You're on a roll — Step 1: Identify the given values. The slant height is l = 45 cm. The radius of the base is r = 28 cm. Step 2: Write down the formula for the total surface area of a cone. The total surface area (TSA) of a cone is given by the formula: TSA = r (r+l) Step 3: Substitute the given values into the formula. Substitute r = 28 cm and l = 45 cm into the formula: TSA = (28 cm) (28 cm + 45 cm) Step 4: Calculate the total surface area. TSA = (28 cm) (73 cm) TSA = 2044 cm^2 If we use ≈ 3.14159: TSA ≈ 2044 × 3.14159 cm^2 TSA ≈ 6421.15 cm^2 The total surface area of the cone is 2044 cm^2 or approximately 6421.15 cm^2. What's next?
