Answer 3

The area of a circle (or circular face) is Pi times the radius squared.
We'll use 3.14 to approximate Pi.

They told us that the diameter (distance across the circular face) is 10.66.
The radius is half of that length.
Divide the diameter by 2 to calculate the radius.

Then we want to plug that radius value into our formula for area.\[\Large\bf\sf A=3.14 (r)^2\]
