Question

HELP

Answer 1

Answer:

He confused the height and diameter

Step-by-step explanation:

Given that,

The radius of the cylinder, r = 2.5 cm

Height of the cylinder, h = 24 cm

The volume of the cylinder is given by the formula as follows :

$V=\pi r^2 h\\\\=3.14\times (2.5)^2\times 24\\\\=471\ cm^3$

Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).
