Have a nice day
Step-by-step explanation:
Given: Radius of hemisphere = 5 cm
Curved surface area is given by,
Curved surface area = 2πr^2
= 2 × 3.14 × 5^2
= 157
Total surface area is given by,
Total surface area = 3πr^2
= 3 × 3.14 × 5^2
= 235.5
Thus, curved surface area of hemisphere is 157 cm^2 and total surface area of hemisphere is 235.5 cm^2.
Hope i helped you :D
