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` cm2

= 942.86 cm2

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

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

= 2093.3 cm3

Total surface area = 942.86 cm2 and volume = 2093.3 cm3

  Is there an error in this question or solution?
