Answer 2

201.06 square units.

EXPLANATION

The area of a circle is calculated using the formula,

`Area = \pi \: {r}^(2)`

The given circle has radius, r=8 units.

We substitute the radius into the formula to obtain:

`Area = \pi * {8}^(2)`

The exact area is 64π square units.

When we substitute π=3.14, we get,

Area=201.06 units square.
