Question

he total surface area of a solid hemisphere of diameter 2 cm is equal to

Answer 1

$\huge\rm\red{Answer :-}$

Total surface area of hemisphere =2πr^2 + πr^2

Given, diameter =2 cm

Therefore, radius =1 cm.

Therefore, total surface area is 3πr^ 2

=3 × π × (1)^2

___________

=3π sq.cm.

___________

Answer 2

3π sq cm

Step-by-step explanation:

given diameter=2cm

therefore radius=1cm

therefore total surface area is

3πr^2

=3*π*(1)^2

=3π sq cm
