What is the total surface area of a cone, if the slant height and radius of a cone is 30 cm and 14 cm, respectively?

1980 cm3 1963 cm3 1908 cm3 1936 cm3

1936 cm3

We know that, Total surface area of cone = πr(r + l) Slant height of cone l = 30 cm Radius of cone r = 14 cm = \(\frac{22}{7}\) × 14 × (14 + 30) = 22 × 2 × 44 = 1936 cm2
