Do 540 ÷ 45 as you're first step. Then multiply that by 3/4.
540÷4= 12.
<h2><em>
12 × 3/4 = 9. Awnser</em>: 9</h2>

This solution to this problem is predicated on the fact that the circumference is just:
. A straight line going through the center of the garden would actually be the diameter, which is well known to be two times the radius of the circle, so we can say that the circumference is just:

So, solving for both the radius and the diameter gives us:

So, the length of thes traight path that goes through the center of the guardain is just
, and we can use the radius for the next part of the problem.
The area of a circle is
, which means we can just plug in the radius and find our area:

So, we have found our area(
) and the problem is done.
Answer:
A. 14x14x28
B. The maximum volume is 5488 cuibic inches
Step-by-step explanation:
The problem states that the box has square ends, so you can express volume with:

Using the restriction stated in the problem to get another equation you can substitute in the one above:

Substituting <em>y</em> whit this equation gives:

Now find the limit of <em>x</em>:

Find the length:

You can now calculate the maximum volume:
