Which shape has the greatest volume

Tresset [83]

Hey mate ,

In this particular question we have to find the volume of given objects and compare to find which has the greatest volume.

Lets Solve ,

Cone =

Volume of cone :- 1/3πr²h

putting the known values ,

Volume = 1/3×3.14×5²×7 cubic ft.

Volume :- 183.1 cubic ft.

Sphere

Volume of Sphere = 4/3πr³

putting the known values ,

Volume = 4/3×3.14×5³ cubic ft.

Volume = 523.33 cubic ft.

Cylinder

Volume of Cylinder = πr²h

putting the known values ,

Volume = 3.14×5²×7 cubic ft.

Volume = 549.5 cubic ft.

Hemisphere

Volume of hemisphere = 2/3πr³

Putting the known values ,

Volume = 2/3×3.14×5³ cubic ft

Volume = 261.66 cubic ft. 

Comparing the volume of each object , we can find that the Cylinder has the greatest volume

What is the resulting ordered pair if the value of the independent variable is –2? f(x)=2x^3+3x^2

sesenic [268]

So we say x=-2

so in the equation where ever we see x we plug in like

f(-2)= 2 * (-3)^3 + 3 * (-2)^2

= 2 * -8+ 3 * 4

= -4
(-2,-4)
hope that helps
