Question

Given a soda can with a volume of 36 and a diameter of 4, what is the volume of a cone that fits perfectly inside the soda can? (Hint: only enter numerals in the answer blank). (4 points)

Answer 1

Answer:

12 unit³

Step-by-step explanation:

Soda can is in the form of a cylinder.

So volume of a soda can = $\pi r^{2} h$

where volume of can = 36 unit³

and r = $\frac{4}{2}$ units = 2 unit

Now from the given formula

36 = (2)² (h) π

36 = 4 h × π

h = $\frac{36}{4}=\frac{9}{\pi }$

Now we have to calculate the volume of a cone that fits perfectly inside the can.

Volume of cone $=\frac{1}{3}(\pi r^{2}h)$

Height of cone = height of can = $\frac{9}{\pi }$ unit

Radius of cone = radius of can = 2 unit

volume of cone = $\frac{1}{3}(\pi )(2)^{2}$ × $(\frac{9}{\pi } )$

= 3 × 4

= 12 unit³

Answer 2

First we need to find the heigh of the soda can be rearanging the volume formula, . We can make that  We know that V is 36 and radius is half of the diameter, so radius is 2. 

h = 2.87

Now, we can use the height to figure out the volume of a cone. The volume of a cone is 
R is 2 again and h is 2.87


12.56*.96 = 12.0576
So a cone with a volume of 12.0576 is the largest that will fit into the soda can
