Question

A cylinder measures 5 inches tall and has a base radius of 8 inches. How does the cylinder's lateral area compare to the sum of the areas of the two bases?

Answer 1

Step-by-step explanation:

We have the two formulae:

`A _(l) = 2\pi rh\\ Ab =\pi r^(2)`

Since there are two bases we multiply Ab by 2.

`2 r\pi h < 2\pi r^(2) \\251.37 < 402.12 (inch)\\\\\\`

The sum of the areas of the 2 bases is bigger.
