Respuesta :

Volume of a sphere is 4/3 pi r^3
Volume = 4/3 pi (3)^2
Volume = 113.1
But there is a half sphere so the volume will be 113.1/2 = 56.55


Volume of a cone = (1/3) pi x r^2 x h
Volume = 1/3 x pi x 3^2 x 7
Volume = 65.97

Total volume = 56.55 + 65.97 = 122.52 in^3

So the correct option is option B
