the total surface area of solid hemisphere is 462 cm square if the curved surface area of its 308 cm square , then the area of the base of its hemisphere
Answers
Given data :
The total surface area of solid hemisphere is 462 cm². If it's curved surface area is 308 cm². Then the area of the base of hemisphere.
Solution : Now, we use formula total surface area of hemisphere.
⟹ Total surface area of hemisphere
= curved surface area of hemisphere + area of circle
⟹ 462 = 308 + area of circle
⟹ area of circle = 462 - 308
⟹ area of circle = 154 cm²
Here, we know that area of is base of the solid hemisphere.
Answer : Hence, area of base of the solid hemisphere is 154 cm².
