Answer:

The area of circle is 232.23 cm²

Step-by-step explanation:

The formula used to calculate area of circle is: [tex]\mathbf{A=\pi r^2}[/tex]

Where [tex]\pi[/tex] = 3.14 and r is radius

We are given radius r = 8.6 cm

We need to find area of circle.

Using formula and finding area of circle

[tex]A=\pi r^2\\A=3.14\times(8.6)^2\\A=3.14\times 73.96\\A= 232.23 \ cm^2[/tex]

So, the area of circle is 232.23 cm²
