Answer:
24
Step-by-step explanation:
area of circle = πr²
πr² = 144π
Cancel out π
r² = 144
r = √144
r = 12
diameter = 2 x radius
diameter = 2 x 12
diameter = 24m
* diameter is the "width of a circle", the distance from the widest points of the circle
X should equal 11
2(3)2-1
6(2)-1
12-1
11
It is about 41.4% according to my TI-83/84 calculator.
Ten times two is equal to twenty.
