10*7*5=350 in3, the volume of 1 brick
14,000 in3 is the volume of all the concrete
Let X=the number of bricks
350*X=14000
X=14000/350
X=40 bricks
To find the x-intercept, substitute in
0
for
y
and solve for
x
. To find the y-intercept, substitute in
0
for
x
and solve for
y
.

16:29:15 I think that would be it but, I'm really sorry if that's not right
Hi I don't know has to do this
The area of the circle is πr², ie. 144π.
The volume of the cilinder is 12×144π = 1728π cm³.
I vote for answer A.
