Question

if the total surface area of a solid hemisphere is 12 pi CM square find its curved surface area

Answer 1

TSA OF HEMISPHERE = 3πr^2
12π^2=3πr^2
12π/3π=r^2
r=√4
r=2cm
CSA=2πr^2
2*π*4
CSA of hemisphere will be =8πcm^2
HOPE IT HELPS

Answer 2

Answer:

Step-by-step explanation:

Total surface area = 12πcm^2

3πr^2 = 12πcm^2

r^2= 12π/3π

r^2= 4

r= 2 cm

Curved surface area of hemisphere = 2 πr^2

= (2*22*2*2)/7

= 25.14 cm^2
