Answer:
A=28.26 in²
Step-by-step explanation:
We are given the formula for the area of a circle which is:
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
