Question
The lateral area is thrice as big as the base area of a
solid cone. If the diameter of the solid cone is 1 meter, then what is the total surface area of solid cone?Solution
Diameter of the cone is 1 meter ⇒ Radius of the cone (r) = 1/2 meter Area of the base of the cone = π(1/2)2 = π/4 Sq. m. The lateral area is thrice as big as the base area ⇒ Lateral area of the cone is 3π/4 Sq. m. Total surface area of the cone = π/4 + 3π/4 ⇒ π Sq. m. ∴ The total surface area of the solid cone is π Sq. m.
