Answer:

C and D

Step-by-step explanation:

The length of the sides will be irrational if it is not a whole number. The tile installer has a square shape, so the formula for area is

area= $side^{2}$

Since we need to find if the side has the whole number, we can make the function to solve for side

side= $\sqrt{area} }$

Then the side for each tile installer will be:

A= $\sqrt{25 in^{2} }$ = 5 inch

B= $\sqrt{36 in^{2} }$ = 6 inch

C= $\sqrt{46 in^{2} }$ = 6.78 inch

D= $\sqrt{60 in^{2} }$ = 7.74 inch

Both C and D have irrational sides

Usimov [2.4K]

The two curves intersect at two points, (0, 0) and (8, 8):

$x^2=8y\implies y=\dfrac{x^2}8$

$y^2=\dfrac{x^4}{64}=8x\implies\dfrac{x^4}{64}-8x=0\implies\dfrac{x(x-8)(x^2+8x+64)}{64}=0$

$\implies x=0,x=8\implies y=0,y=8$

The area of a semicircle with diameter $d$ is $\dfrac{\pi d^2}8$ . The diameter of each cross-section is determined by the vertical distance between the two curves for any given value of $x$ between 0 and 8. Over this interval, $y^2=8x\implies y=\sqrt{8x}$ and $\sqrt{8x}>\dfrac{x^2}8$ , so the volume of this solid is given by the integral
