Answer:
A = 9 pi cm^2
Step-by-step explanation:
Circumference = 2 * pi *r
6pi = 2 * pi *r
Divide each side by pi
6 = 2r
Divide by 2
6/2 = 2r/2
3=r
Now we want to find the area
A = pi r^2
A = pi (3)^2
A = 9 pi cm^2
Answer: [tex]28.27cm^2[/tex]
Step-by-step explanation:
The area of a circle can be calculated with the formula:
[tex]A=\pi r^2[/tex]
Where r is the radius of the circle.
The circumference of a circle can be calculated with the formula:
[tex]C=2\pi r[/tex]
Where r is the radius of the circle.
Knowing that the circumference is 6π, you know that the radius is:
[tex]r=\frac{6\pi}{2\pi}\\r=3cm[/tex]
Substitute the radius of the circle into the formula [tex]A=\pi r^2[/tex], then:
[tex]A=\pi (3cm)^2\\A=28.27cm^2[/tex]
