12inches because 3 is pi and 2 is Radius so 3x2squared=12
Step-by-step explanation:
length of mall=84m
length of post office=38m
how much longer is the mall than the post office=84-38= 46m
If she picks 2/4 in half an hour she must pick 1.5 in an hour (2/4 x 2) so times that by 2 then its 3

Answer:
A) 504
B) 8
Step-by-step explanation:
The statement of proportionality can be written as the equation ...
m = kr²
Then we can find k from ...
k = m/r² = 14/2² = 7/2
That is, ...
m = (7/2)r²
__
Using this relation, we can find m for r=12:
m = (7/2)·12² = 7·72
m = 504 . . . for r = 12
__
And, we can use the same equation to solve for r when m=224.
224 = 7/2·r²
r² = 64
r = √64
r = 8 . . . for m = 224
