Answer:

28.3 square meters.

Step-by-step explanation:

So we know that the radius of the circle is 3 meters. With that, we can figure out the area of the circle.

The area of a circle is given by the formula:

[tex]A=\pi r^2[/tex]

Plug in 3 for r:

[tex]A=\pi (3)^2[/tex]

Square the number:

[tex]A=9\pi[/tex]

Use a calculator. Approximate:

[tex]A\approx28.2743\approx28.3[/tex]

Therefore, the area of the circle is approximately 28.3 square meters.

Answer:

28.3 m²

Step-by-step explanation:

The area of a circle can be found using the following formula.

[tex]a=\pi r^2[/tex]

We know the radius of the circle is 3 meters. We can substitute 3 m in for the variable, r.

[tex]a= \pi (3m)^2[/tex]

Evaluate the exponent.

(3m)² = 3m * 3m= 9 m²

[tex]a= \pi (9 m^2)[/tex]

Multiply pi and 9 meters squared.

9 m² * π = 28.2743339 m²

[tex]a=28.2743339 m^2[/tex]

Round to the nearest tenth. The 7 in the hundredth place tells us to round the 2 in the tenth place to an 3

[tex]a\approx 28.3 m^2[/tex].

The area is approximately 28.3 square meters.
