r = 4.0 units

Given that,

A cylinder has a radius of r units, and that the height of the cylinder is also r units.

The lateral area of the cylinder is 98 square units.

We need to find the value of r.

The formula for the lateral area of the cylinder is given by:

$\text{A}=2\pi \text{rh}$

Put all the values,

$2\pi \text{rh}=98$

$\text{r}=\sqrt{(98)/(2\pi) }$

$\text{r}=4.0 \ \text{units}$

So, the value of r is equal to 4.0 units.
