The area in this case would be 3.14 :)
Answer:
C
Step-by-step explanation:
So solve for the placeholder D
D/12=0.25
multiply both sides by 12 to clear fraction
12D/12=0.25 times 12
D(12/12)=3
D(1)=3
D=3
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

=18.33
=18.3 (corr. to the nearest tenth)
