WebLet, the radius and height of the cylinder ber and h respectively. ∴ Volume of the original cylinder=πr2h. According to the question, New radius = r and new height = 2h. ∴ Volume of the new cylinder =π(r)2(2h) = 2πr2h. ⇒ The volume will become double of the original volume. Hence, option (A) is the correct answer. Suggest Corrections. WebTherefore, the curved surface area of the cone is 165 cm 2. 2. Find the total surface area of a cone, if its slant height is 21 m and the diameter of its base is 24 m. (Assume π = 22/7) Solution: Radius of cone, r = 24/2 m = 12m. Slant height, l = 21 m. Formula: Total Surface area of the cone = πr(l+r) Total Surface area of the cone = (22/7 ...

The space occupied by a two-dimensional flat surface is called the area. It is measured in square units. The area occupied by a three-dimensional object by its outer surface is called the surface area. It is also measured in square units. Generally, Area can be of two types: (i) Total Surface Area (ii) Curved … See more The amount of space, measured in cubic units, that an object or substance occupies is called volume. Two-dimensional doesn’t have volume but has area only.
