Question

If the tsa of hemisphere is 1587cm^2 then length of diameter is

Answer 1

Answer:

Diameter (d) = 25.94 cm

Explanation:

Let radius of the hemisphere

= r cm

TSA = 1587 cm²

=> 3πr² = 1587 cm²

=> 3×(22/7)×r² = 1587 cm²

=> r² = (1587 × 7 )/(3×22)

= (529×3×7)/(3×22)

=(529×7)/22

=> r² = 168.3181

=> r ≈ 12.97

Now ,

Diameter (d) = 2r

= 2×12.97

= 25.94 cm
