A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

8 in3
24 in3
48 in3
72 in3

Respuesta :

The correct answer is letter D. 72 in3

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = [tex]\frac{1}{3}\pi r^{2} h[/tex]   --1

Volume of cylinder = [tex]\pi r^{2} h[/tex]  --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

[tex]\text{Volume of cone}= \frac{1}{3} \text{Volume of cylinder}[/tex]

Since we are given the volume of cone is 24 cubic inches .

So, [tex]24= \frac{1}{3} \text{Volume of cylinder}[/tex]

[tex]24 \times 3= \text{Volume of cylinder}[/tex]

[tex]72= \text{Volume of cylinder}[/tex]

Hence the volume of cylinder is 72 cubic inches

Option D is correct.
