Frustum volume |

Answer» Pta nhi mai to gussa nhi hu us se sowndu smarkee kha h Yhi hu bolo Hii kaha gaya thu Frustum of a cone:Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.e.g. Flower pots have a shape as the frustum of a cone.The surface area and the volume of the frustum of a cone can be calculated using standard formulae.CSA of the frustum of a cone =\xa0πl( r1\xa0+ r2).where r1\xa0= radius of the larger circular face of the frustum, r2\xa0= radius of the smaller circular face of the frustum, and l = slant height of the frustum.l =\xa0h2+(r1-r2)2h2+(r1-r2)2 and h is the height of the frustum.TSA of a frustum of a cone = πl(r1\xa0+ r2) + πr12\xa0+ πr22Volume of the frustum of a cone = (1/3) πh (r12\xa0+ r22\xa0+ r1\xa0r2) Hi |
