Question

If the radius of a solid hemisphere is 5cm then find its curved surface area and
total surface area.​

Answer 1

Answer:

Solution. Thus, the curved surface area and total surface area of the solid hemisphere is 157 cm2 and 235.5 cm2, respectively.

Answer 2

Answer:

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.
