The lateral surface area of a cuboid is given by 2(length + breadth) × height. Similarly, the lateral surface area of a cube of side “a” is equal to 4 × (side) 2. Lateral Area for Cylinder. The Curved or lateral Surface Area of a Cylinder is given by 2 × π × r × h where, r = base radius, and h = height of the cylinder. The total ...
The lateral surface area is the surface area of the sides of any three dimensional figure. Each figure may have a different base, but the lateral surface area is found the same way. Find the ...
The lateral surface area of a three-dimensional object is the surface area of the object minus the area of its bases. For example, consider our die. We found that the surface area of a six-sided ...
Surface area formulas in geometry refer to the lateral surface and total surface areas of different geometrical objects. To recall, the surface area of an object is the total area of the outside surfaces of the three-dimensional object i.e, the total sum of the area of the faces of the object. It is measured in terms of square units.
Lateral area = 2 x 3.14 x (16)\(^2\) = 1607.68 cm Hence, the lateral area for the sphere is 3215.36 cm² and the lateral surface area of a hemisphere is 1607.68 cm² respectively. Example 3: Find the lateral area of a cylinder with radius 8 units and height 14 units. Take π = \(\frac{22}{7}\). Solution: As provided,
Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units. The above formula gives the total surface area of a cuboid having all six faces. Lateral Surface Area of a Cuboid. The lateral surface area of a cuboid is the sum of 4 planes of a rectangle, leaving the top (upper) and the base (lower) surface.
(ii) Curved Surface Area/Lateral Surface Area. Total Surface Area. Total surface area refers to the area including the base(s) and the curved part. It is the total area covered by the surface of the object. If the shape has a curved surface and base, then the total area will be the sum of the two areas. Curved Surface Area/Lateral Surface Area
A pyramid’s lateral surface area is the sum of the areas of all its side faces (which are triangles). Lateral Surface Area \(=\left ( \frac{1}{2} \right )PH\) can be used to calculate the lateral surface area of a pyramid, where ‘P’ is the base perimeter and ‘H’ is the slant height.
What is the radius of the barrel if its lateral surface area is 50 square meters? [Take π = 3.14] Solution: As stated in the question: Height, h of the cylindrical barrel = 1.2 meters Lateral surface area of the cylindrical barrel = 50 square meters Apply the formula for the lateral surface area of the cylinder: Lateral Surface Area of ...
The surface area of a sphere formula is given by, A = 4 π r 2 square units. For any three-dimensional shapes, the area of the object can be categorised into three types. They are: Curved Surface Area; Lateral Surface Area; Total Surface Area; Curved Surface Area: The curved surface area is the area of all the curved regions of the solid.
