A cylinder has a volume of 78cm3 What is the volume of a cone with the same radius and height class=

Respuesta :

Answer:Volume of cylinder V= bh= 78 cm^3,


where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3Upvote•0Downvote Add comment

Answer :D

The volume of the cone is [tex]26^{}[/tex] [tex]cm^{3}[/tex]

Question explanation:

Okay, so, we know that.

The volume of a cylinder is equal to:

[tex]V^{}[/tex] [tex]=[/tex] [tex]\pi[/tex][tex]r^{2}[/tex][tex]h[/tex]

In this problem, we have that:

[tex]V[/tex] [tex]=[/tex] [tex]78[/tex] [tex]cm^{3}[/tex]

So:

[tex]78 =[/tex] [tex]\pi[/tex][tex]r^{2}[/tex] [tex]h[/tex] [tex]=[/tex] [tex]equation[/tex] [tex]A[/tex]

The volume of a cone with the same radius and height is equal to

[tex]V =[/tex] [tex]\frac{1}{3}[/tex] [tex](\pi r^{2} h)[/tex] [tex]= equation[/tex] [tex]B[/tex]

Substitute equation A in equation B

[tex]V = \frac{1}{3} (78)[/tex]

[tex]V = 26^{}[/tex] [tex]cm^{3}[/tex]
