Calculate the Base Circumference, Volume

Calculatethe Curved Surface Area, Base Surface. Total Surface Area

Hemisphere

Calculate Base Circumference:

Base Circumference = 2πr

Base Circumference = 2π(12)

Base Circumference = 24π or 75.3982

Calculate Volume (V):

V  =  2πr3
  3

V  =  2π(123)
  3

V  =  2π(1728)
  3

V  =  3456π
  3

V = 1152π or 3619.1147

Calculate Curved Surface Area:

Curved Surface Area = 2πr2

Curved Surface Area = 2π(122)

Curved Surface Area = 2π(144)

Curved Surface Area = 288π or 904.7787

Calculate Base Surface Area:

Base Surface Area = πr2

Base Surface Area = π(122)

Base Surface Area = π(144)

Base Surface Area = 144π or 452.3893

Calculate Total Surface Area:

Total Surface Area = Curved Surface Area + Base Surface Area

Total Surface Area = 288π + 144π

Total Surface Area = 432π or 1357.168

Final Answers:

Base Circumference = 24π or 75.3982
V = 1152π or 3619.1147
Curved Surface Area = 288π or 904.7787
Base Surface Area = 144π or 452.3893
Total Surface Area = 432π or 1357.168





What is the Answer?
Base Circumference = 24π or 75.3982
