Answer 2

Given,

Total surface area of hemisphere = 462 cm²

Curved surface area of hemisphere = 308 cm²

To find,

The base area of the hemisphere.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Total surface area of a hemisphere = Curved surface area + Base area

So,

Base area = Total surface area - Curved surface area

Base area = 462 - 308 [Putting the given values]

Base area = 154 cm²

(This will be the area of base of the given hemisphere.)

Hence, the area of the base of the given hemisphere is 154 cm².
