A circle has a radius of 3.4 meters. What is the area of the circle?

A. [tex]21.4 \, m^2[/tex]
B. 21.4 m
C. [tex]36.3 \, m^2[/tex]
D. 36.3 m

Answer :

To find the area of a circle, we use the formula

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

where [tex]$r$[/tex] is the radius. In this problem, the radius is given as [tex]$r = 3.4$[/tex] meters.

1. First, we calculate the square of the radius:

[tex]$$
r^2 = (3.4)^2 = 11.56.
$$[/tex]

2. Next, we substitute [tex]$r^2$[/tex] into the area formula:

[tex]$$
A = \pi \times 11.56.
$$[/tex]

3. Multiplying by [tex]$\pi$[/tex] gives approximately

[tex]$$
A \approx 36.3168 \text{ m}^2.
$$[/tex]

4. Rounding to one decimal place, the area of the circle is approximately

[tex]$$
A \approx 36.3 \text{ m}^2.
$$[/tex]

Thus, the area of the circle is

[tex]$$\boxed{36.3 \text{ m}^2}.$$[/tex]
