Curved Surface Area = 2πrh
Curved Surface Area = 2πrh, use this fromula to find radius.
The different formula of a cylinder
Total Surface Area = \\(2 \\times\\) Area of the triangular base + Sum of the areas of the three rectangular faces
The total surface area of a cylinder is given by the formula: TSA = 2πrh + 2πr^2, check by assuming values.
Use the area of a circle
The area of a regular hexagon can be calculated using the formula: .(3√3 * side length^2) / 2
Use the formula to find a surface area of a triangular prism.
The surface area of the pentagonal prism is given by, Where, a = Apothem length of the prism b = Base length of the prism h = Height of the prism
