Multiple choice

The ice cream cone height is double its radius. The radius is $5.5$ cm. Find the volume of a cone.

  1. $\displaystyle 110.126{ cm }^{ 2 }$
  2. $\displaystyle 110.916{ cm }^{ 2 }$
  3. $\displaystyle 348.27{ cm }^{ 3 }$
  4. $\displaystyle 345.425{ cm }^{ 2 }$

C Correct answer
Explanation

The height is 11 cm because it is twice the radius. The volume is 1/3 times pi times 5.5^2 times 11, approximately 348.27 cm^3, so option C has the correct numerical value, although its unit should be cm^3 rather than cm^2.

AI explanation

Given the radius is 5.5 cm and the height is double the radius, the height is 11 cm. Using the cone volume formula V = 1/3*pi*r^2*h, the volume is 1/3 * 3.14 * (5.5)^2 * 11 = 348.27 cm^3.
