Question

a toy is in the form of a cone mounted on a hemisphere of same radius. The total surface area of the toy is​

Answer 1

the total surface area of the toy is the sum of the lateral surface area of the cone and the curved surface area of the hemisphere. Therefore, the total surface area (TSA) of the toy = LSA of the cone + CSA of the hemisphere. Therefore, the total surface area (TSA) of the toy = 137.5 + 77 = 214.5 cm2.

Answer 2

Answer:

So, the total surface area of the toy is the sum of the lateral surface area of the cone and the curved surface area of the hemisphere. Therefore, the total surface area (TSA) of the toy = LSA of the cone + CSA of the hemisphere. Therefore, the total surface area (TSA) of the toy = 137.5 + 77 = 214.5 cm2
