Find the total surface area and volume of a hemisphere whose radius is 10 cm.

###### Advertisements

#### Solution

Radius = 10 cm

Total surface area = `3pir^2`

= `3 xx 22/7 xx 10 xx 10` cm^{2}

= 942.86 cm^{2}

Volume of hemisphere = `2/3pir^3`

= `2/3 xx 3.14 xx 10 xx 10 xx 10 "cm"^3`

= 2093.3 cm^{3}

Total surface area = 942.86 cm^{2} and volume = 2093.3 cm^{3}
