Answer:

A=28.26 in²

Step-by-step explanation:

We are given the formula for the area of a circle which is:

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

Which means:

Area = π*radius of circle²

The radius of a circle is the length from the center of the circle to the edge of the circle.

The image tells us the radius of the circle is 3 in and the questions asks us to use 3.14 for π, therefore...

A=3.14*3²

A=3.14*9

A=28.26 in²

Answer:

  • 28.26 in²

Step-by-step explanation:

We know that:

  • Area of circle = πr²
  • Radius = 3 in.
  • π = 3.14

Solution:

  • πr² = Area of circle
  • => 3.14 x 3² = Area of circle
  • => 3.14 x 9 = Area of circle
  • => 28.26 in² = Area of circle

Hence, the area of the circle is 28.26 in².
