Nikolay [14]

Answer:

$4\sqrt{\pi}$

Step-by-step explanation:

The cross section of a sphere is a circle with area $\pi r^2$ , where radius is given as 4
The cross section of the cube is a square with area $a^2$ , where a is side length of square

The circle area = the square area. Thus we have:

$\pi r^2 = a^2 \\\pi(4)^2=a^2\\16\pi=a^2\\\sqrt{16\pi}=a\\ a=\sqrt{16} \sqrt{\pi} \\a=4\sqrt{\pi}$

Answer:

4.5

Step-by-step explanation:

The value of x that makes f(x) = -3 is ...

4/3x -9 = -3

4/3x = 6 . . . . . . add 9

x = 6(3/4) = 18/4 = 9/2 = 4.5 . . . . multiply by 3/4
