What is a sphere made up of?

soldier1979 [14.2K]

In my opinion, the correct answer among the choices listed above is option B. A sphere made up of many circular cross sections. When you cut through a plane at any angle or side, you will see that the plane made will always be a circle.

Find the missing length indicated. Leave your answer in simplest radical form.

musickatia [10]

Answer:

1). x = 81

2). x = 84

Step-by-step explanation:

1). By applying geometric mean theorem in the given triangle,

$\frac{x}{18\sqrt{14}}= \frac{18\sqrt{14}}{56}$

56x = (18√14)²

56x = 4536

x = $\frac{4536}{56}$

x = 81

2). By applying geometric mean theorem,

$\frac{x}{8\sqrt{21}}= \frac{8\sqrt{21} }{16}$

16x = (8√21)²

16x = 1344

x = $\frac{1344}{16}$

x = 84
