In this circle, the area of sector COD is 50.24 square units. The radius of the circle is units , and units.

maks197457 [2]

Let angle be alpha

$\\ \rm\Rrightarrow Area=50.24$

$\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24$

$\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4$

$\\ \rm\Rrightarrow \alpha r^2=5760$

$\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}$

$\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}$

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer

Kisachek [45]

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:

$v=x^{2} y$

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

$4x+y=84\\\\$

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

$v=x^{2} (84-4x)\\\\v=84x^{2} -4x^{3}$

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

$\frac{84x^{2}-4x^{3}}{dx}=168x-12x^{2}\\\\x=\frac{168}{12}=14$

Find the length:

$y=84-4(14)=28$

You can now calculate the maximum volume:

$v=(14)^{2}(28)= 5488$
