Step 5: Add both parts to get the total surface area Now, add both parts together: Total Surface Area=2310+1386=3696cm2 Final Answer The total surface area of the cone is: Total Surface Area=3696cm2 View Solution If the area of the circular shell having inner and outer radius of 8 ...
题目The total surface area of a cone is equal to ___. A. LSA + BA B. LSA - BA C. LSA×BA D. LSA÷BA 相关知识点: 试题来源: 解析 A。中文解析:圆锥的总面积等于侧面积加上底面积,即 TSA = LSA + BA。反馈 收藏
Surface Area of Base= π× r2 = π× 22 = 4π ≈ 12.57 Surface Area of Side= π× r ×√(r2+h2) = π× 2 ×√(22+72) = π× 2 ×√(4+49) = 2π√(53) ≈ 45.74 Total Surface Area ≈ 12.57 + 45.74 ≈ 58.31Volume...
Furthermore, if a circle whose area is πr2 is used to close the base. Then, the total surface area = πrl +πr2. Therefore, Total Surface Area of a Cone = πr (l+r) Browse more Topics under Surface Areas And Volumes Cuboid and Cube Sphere Cylinder Frustum of Cones Combination of...
Volume of Cone = Curved Surface Area(CSA) of Cone: [ πrl ] Enter the radius = Enter the height = Curved Surface Area(CSA) of Cone = Total Surface Area(TSA) of Cone: [ πr(l+r) ] Enter the radius = Enter the height = Total Surface Area(TSA) of Cone = Next...

Surface area isa total area that the surface of the object occupies. In other words, it’s the total area of the surface of a 3D object. Sometimes the surface area may be split into a sum ofbase area(s)andlateral surface area. The lateral surface is the area of all the sides of th...
Volume of Cone = (1/3)πr² h Curved Surface Area (CSA) of Cone = πrl Total Surface Area (TSA) of Cone = πr(l + r) where, r = radius, l = slant height, h = height, π = 3.14 A Cone is a geometric shape formed by having a circle at one end, usually at a base....
Adding the lateral area to the result for the area of the base of the cone, we get A, the total surface area of a right cone: A=(π⋅r2)+(π⋅r⋅l)A=(π⋅r2)+(π⋅r⋅l) This can then be simplified to: A=π⋅r⋅(r+l)A=π⋅r⋅(r+l) If you only kno...
