A circular mirror has the diameter of 12 inches. what is the area in square inches?

nika2105 [10]

Hello!

To find the area of a circle you do $\pi r^{2}$

Where r stands for radius.

The radius is just half the diameter

So you put that into a calculator and get 113.1 $in^{2}$

Hope this helps!

How do find the answer

soldier1979 [14.2K]

Well to find the measure of angle B you you just add angle C and A so 53+90= 143 and then subtract that from 180 so, 180-143= 37 so <B=37 degrees.
