Question

write the farmula to find the total surface area of a hemisphere
​

Answer 1

$\huge\colorbox{violet}{❥︎Answer}$

Total surface area of a hemisphere: A = 3 * π * r²

Surface to volume ratio of a hemisphere: A / V = 9 / (2 * r) .

Answer 2

Answer:

=3πr2

Step-by-step explanation:

formula =3πr2

Curved surface area of hemisphere

=2πr2

Total surface area of hemisphere 

=3πr2

Ratio between them 

2πr2:3πr2

i.e;2:3
