Question

Explain the Error. A student said the volume of a cylinder with a 3- inch diameter is two times the volume of a cylinder with the same height and a 1.5 inch radius. What is the error?

Answer 1

See explanation

Explanation:

Because the formula for the volume of a cylinder is
`\pi r^2 h`, when you multiply the radius by 2, the volume increases by
`2^2=4` times. Hope this helps!
