Calculate the Base Circumference, Volume

Calculatethe Curved Surface Area, Base Surface. Total Surface Area

Hemisphere

Calculate Base Circumference:

Base Circumference = 2πr

Base Circumference = 2π(5)

Base Circumference = 10π or 31.4159

Calculate Volume (V):

V  =  2πr3
  3

V  =  2π(53)
  3

V  =  2π(125)
  3

V  =  250π
  3

V = 83.333333333333π or 261.7994

Calculate Curved Surface Area:

Curved Surface Area = 2πr2

Curved Surface Area = 2π(52)

Curved Surface Area = 2π(25)

Curved Surface Area = 50π or 157.0796

Calculate Base Surface Area:

Base Surface Area = πr2

Base Surface Area = π(52)

Base Surface Area = π(25)

Base Surface Area = 25π or 78.5398

Calculate Total Surface Area:

Total Surface Area = Curved Surface Area + Base Surface Area

Total Surface Area = 50π + 25π

Total Surface Area = 75π or 235.6194

Final Answers:

Base Circumference = 10π or 31.4159
V = 83.333333333333π or 261.7994
Curved Surface Area = 50π or 157.0796
Base Surface Area = 25π or 78.5398
Total Surface Area = 75π or 235.6194
