The surface area of a frustum of a cone is given by: Surface Area = πl(r₁ + r₂) + π(r₁² - r₂²) Where l is the slant height, r₁ and r₂ are the radii of the two ends. Substitute the values: Surface Area = 3.14 × 13 × (8 + 5) + 3.14 × (8² - 5²) Surface Area = 3.14 × 13 × 13 + 3.14 × (64 - 25) Surface Area = 3.14 × 169 + 3.14 × 39 Surface Area = 3.14 × 208 Surface Area = 653.12 cm² Correct Option: d
