WebThe curved surface area of a right circular cylinder of height 14 cm is 88 cm 2. Find the diameter of the base of the cylinder. Solution: Let the radius and height of the cylinder be 'r' and 'h' respectively. Curved Surface Area of a right circular cylinder = 2 π r h. Diameter = 2 × radius. Height of the cylinder, h = 14 cm. CSA of the ... WebThe formula for the lateral surface area of a cone, 𝐴 L, is 𝐴 = 𝜋 𝑟 𝑙, L where 𝑟 represents the base radius of the cone and 𝑙 represents the slant height. The formula for the total surface area of a cone, 𝐴 T, is 𝐴 = 𝜋 𝑟 𝑙 + 𝜋 𝑟. T . We must be careful to make …

WebDec 2, 2024 · C.S.A of each cone = πrℓ = 3.14 × 0.2 × 1.02 m 2 = 0.64056 m 2 ⇒ C.S.A of 50 cones = 50 × 0.64056 m 2 = 30.028 m 2 = Area to be painted ∵ The cost of painting is Rs. 12 per m 2 ∴ The total cost of … WebOct 28, 2024 · The curved surface area (CSA) is the total area occupied by the cone in a three-dimensional plane. Therefore, the curved surface area of a cone is equal to the product of the radius of the circular base and the slant height of the cone. There are two types of cones – right circular cone and oblique cone. software developer in gurgaon

WebThe total surface area of a cone with slant height and diameter of the cone can be found by using the formula, T = π(D/2) ((D/2) + l), where D is the diameter and l is the slant height. The curved surface area of the cone with slant height and diameter can be found by using the formula S = π(D/2)l, where D is the diameter and l is the slant ... WebCSA of cone = πrl "r" and "l" stands for radius and slant height of cone. Example 1 : If the vertical angle and the radius of the right circular cone are 60 degree and 15 cm respectively, then find its slant height and curved surface area. ... Radius and slant height of a solid right circular cone are in the ratio 3:5. r : L = 3 : 5 ... WebThe curved surface area of a right circular cone equals the perimeter of the base times one-half slant height. The total surface area equals the curved surface area of the base. Example: The slant height of a conical tomb is … software developer in dubai salary
