Answer 1

Find the volumen of the semisphere and subtract the volumes of the two cylinders

1) Volume of the semisphere:

[1/2] (4/3)π(r^3) =[ 2π(1.5m)^3 ]/3 = 7.0686 m^3

2) Volumen of the cylinders:π(r^2)h

a) π(0.75/2m)^2 (1.75m) = 0.7731 m^3

b) π(1/2m)^2 (1.25m) = 0.9818 m^3

3) 7.0686 m^3 - 0.7731 m^3 - 0.9818m^3 = 5.3137 m^3

Answer: 5.3 m^3
