$201.06 {cm}^(2)$

Explanation:

The value of pi is around 3.1415927

The formula to find the area is a circle is ;

$\pi {r}^(2)$

We know that the radius(r) is 8cm

You put 8 at where the r is.

so u have

$3.1415927 * {8}^(2)$

${8}^(2) = 64 \\ 3.1415927 * 64 \\ 201.0619328$

U then round your answer.

Hope this helps.

Answer:

64π cm²

Explanation:

You want the exact area of a circle of radius 8 cm.

The area of a circle is given by ...

A = πr²

Using the given value of radius, we find the area to be ...

A = π(8 cm)² = 64π cm²

The area of the circle is 64π square centimeters.

Additional comment

The "exact" area can only be expressed using a symbol for the irrational number pi.
