The radius of a hemisphere is 4.5 cm. Find its surface area and its volume.

Answer :

Hemisphere is half of a sphere

So the volume and area will be halved

But for total surface area there would be one more area which is the flat circle of a hemisphere

Radius of hemisphere = r = 4.5 cm =

Surface area of hemisphere = 3πr2

= 3 × ×

= 3 × ×



= 190.92 cm2

Volume of hemisphere = πr3

= × ×



= 190.92 cm3

Therefore, surface area is 190.92 cm2 and volume is 190.92 cm3
