To find the area of a circle with a given circumference of 18.84 units, we will follow these steps:
1. Recall the formula for the circumference of a circle:
[tex]\[ C = 2 \pi r \][/tex]
where [tex]\( C \)[/tex] is the circumference and [tex]\( r \)[/tex] is the radius of the circle.
2. Given the circumference [tex]\( C = 18.84 \)[/tex] units, we need to find the radius [tex]\( r \)[/tex]. We can rearrange the circumference formula to solve for [tex]\( r \)[/tex]:
[tex]\[ r = \frac{C}{2 \pi} \][/tex]
3. Substitute the given circumference into the formula to find the radius:
[tex]\[ r = \frac{18.84}{2 \pi} \][/tex]
Evaluating this, we get:
[tex]\[ r \approx 2.998 \][/tex]
4. Once we have the radius, we can find the area of the circle using the area formula:
[tex]\[ A = \pi r^2 \][/tex]
where [tex]\( A \)[/tex] is the area.
5. Substitute the radius into the area formula to find the area:
[tex]\[ A = \pi (2.998)^2 \][/tex]
Evaluating this expression, we get:
[tex]\[ A \approx 28.245 \][/tex]
Therefore, the area of the circle is approximately [tex]\( 28.245 \)[/tex] square units.
