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
25
33
44 - 25% off is 33
5 8
Coefficient of x should be 5 so first ? should be 5 let the second ? = z
5×6-9×z=-42
30+42=9z
z=8
14.31
