WebThe length of each arc will be equal to the circumference of the cone at its base and at the height of the intersecting plane. Firstly the apex angle of the cone needs to be found from the right triangle in the diagram, ie α = tan-1 [ ½ ( C – D ) / H ]. The full slant height of the non-truncated cone can then be found from R2 = ½ C / sin α. Web4. The volume of a prism is indeed base area times height. So what you are calculating with your 1 2 h r × 2 π r is the volume of a prism with triangular base and height 2 π r. This is a very different beast from your cone! If you tried to do the same for a cylinder, then you'd have a rectangle of area r h rotated around a circumference of 2 ...

WebJan 24, 2024 · Q.4. Define the frustum of a cone. Ans: If a plane parallel to its base cuts off a right circular cone, then the portion of the cone between the cutting plane and the base of the cone is called a frustum of the cone. Q.5. Write the formula to find the curved surface area of a frustum of a cone. WebApr 22, 2024 · If you do not know it, you can find the side length ( s) using the radius ( r) and the cone's height ( h ). s = √ (r2 + h2) With that, you can then find the total surface area, which is the sum of the area of the base and area of … graber\u0027s animal hospital toledo ohio
