Given: Radius (r) = 5 cm
To find: Curved surface area and total surface area of hemisphere
i.Curved surface area of hemisphere = 2πr2
= 2 x 3.14 x 52
= 2 x 3.14 x 25
= 50 x 3.14
= 157 sq.cm.
ii.Total surface area of hemisphere = 3πr2
= 3 x 3.14 x 52
= 235.5 sq.cm.
∴ The curved surface area and total surface area of hemisphere are 157 sq.cm, and 235.5 sq.cm, respectively.
