Question

An ice cream cone has a depth of 9 inches and a radius of 2 inches, respectively. The volume of the cone ice cream is .

• A. $12\pi {\text{in}}^3$
• B. $3\pi {\text{in}}^3$
• C. $10\pi {\text{in}}^3$
• D. $4\pi {\text{in}}^3$

Answer 1

The correct option is A $12\pi {\text{in}}^3$

Let's draw the ice cream cone with the given dimensions:


Radius of the cone = r = 2 inches
Depth of the cone = h = 9 inches

We know,
$\text{Volume of a cone}=\frac{1}{3}\pi r^{2}h$

So, putting values we get:
$\text{Volume of the ice cream cone}=\frac{1}{3}\pi \times 2^2\times 9$
$=\pi \times 4\times 3$
$=12\pi {\text{in}}^3$
