Find the volume of the solid where the cone and half sphere are hollow. Use 3.14 for П ; height is 19 in; radius is 5 in. Round
Vera_Pavlovna [14]

Volume of Solids

The volume of the solid is 758.83 in³

Step-by-step explanation:

Given that the cone and half sphere is hollow

The volume of the cone = 1/3 \pi r^{2} h\\

The Volume of the sphere  = 4/3 \pi r^{3}

So the Volume of the half sphere =2/3\pi r^{3}

The volume of solid = volume of cone + volume of the half sphere

V = V_{1}  + V_{2}

Given

height h = 19 in

radius r = 5 in

V_{1\\}  = 1/3 \pi r^{2} h

     = 1/3 × 3.14 × 5 × 5 × 19

     = 497.16 in³

V_{2}  =  2/3 \pi r^{3}

   = 2/3 × 3.14 × 5 × 5 × 5

   = 261.67 in³

V =  497.16 in³ + 261.67 in³

  = 758.83 in³

Hence the volume of the solid is 758.83 in³

What is the value of x?
antoniya [11.8K]
Since the figure is a rhombus, the diagonals cut each other at right-angles and bisect each other, namely cut their vertices in equal halves.

what the dickens does all that mean?  well, the angles at vertex C and vertex A are all twins, and therefore, ∡BCA = x, therefore

\bf (3x-26)+(x)+(90)=180\implies 4x+64=180\implies 4x=116
\\\\\\
x=\cfrac{116}{4}\implies x=29
