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 =
The Volume of the sphere =
So the Volume of the half sphere =
The volume of solid = volume of cone + volume of the half sphere
Given
height h = 19 in
radius r = 5 in
=
= 1/3 × 3.14 × 5 × 5 × 19
= 497.16 in³
= 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
Answer: y - 4 = -12 ( x + 2)
Step-by-step explanation:
The equation of a line in point - slope form is given as :
= m(
)
Where m is the slope and ( ,
) is the given point
substituting the values into the formula , we have:
y - 4 = -12 ( x - {-2})
y - 4 = -12 ( x + 2)
