Total surface area of a lattu (top) as shown in the $Fig.$ is the sum of total surface area of hemisphere and the total surface area of cone.
Total surface area of a lattu (top) as shown in the $Fig.$ is the sum of total surface area of hemisphere and the total surface area of cone.
(FALSE) False.
The total surface area of the lattu (top) is the sum of the curved surface area of the hemisphere and the curved surface area of the cone.
This is because the circular base of the hemisphere and the circular base of the cone are joined together and are not exposed to the outside. Therefore,they are not included in the total surface area of the combined solid.
