Answer:

x is less than 4

x is greater than 4

Step-by-step explanation:

-5x < -15x + 40 -5x < -15x + 40

+15x +15x -40 -40

10x < 40 -40 - 5x < -15x

÷10 ÷10 +5x +5x

× < 4 -40 < -10x

÷10 ÷10

4 < ×

Formulas that may be useful relative to a sphere: V = 43πr3 and SA = 4πr2

Tasya [4]

Finding the radius from it's surface area, the volume of the sphere is of 268.08 cm³.

<h3>What are the surface area and the volume of an sphere?</h3>

For an sphere of radius r, we have that the surface area is given by:

$S = 4\pi r^2$

The volume is given by:

$V = \frac{4\pi r^3}{3}$

Considering the surface area of 200.96 cm², the radius is given by:

$S = 4\pi r^2$

$200.96 = 4\pi r^2$

$r = \sqrt{\frac{200.96}{4\pi}}$

r = 4 cm

Hence the volume is given by:

$V = \frac{4\pi \times 4^3}{3} = 268.08 \text{cm}^3$
