Answer and Step-by-step explanation:
First of all, we are looking to solve for the frame itself. not the inside mirror in the frame.
The formula that is used for this problem is to find the area of a circle.
The formula is: π[tex]r^{2}[/tex]
It also says to use 3.14 for pi.
d = diameter
r = the radius, which is half of the diameter
your diameter here for this problem is 3, so that means your radius is going to be 1.5.
so let us just substitute these variables.
3.14·[tex]1.5^{2}[/tex]
and then solve...
[tex]1.5^{2}[/tex] = 2.25
3.14 · 2.25 = 7.065
The area of the circular mirror's frame: 7.065 ft.
Hope this helps and a thank won't hurt! :)
