Answer:

2x±44

Step-by-step explanation:

-2[x-7]=-2x±14 because negative ×negative=positive

±5[3x±6]=15x±30

-3[5x±10]=-15x±30

2x±14±15x-15x±30

2x±15x-15x=2x

14±30=44

2x±44=2x±44

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 48 cm³.

Taya2010 [7]

Answer:

32 cm³

Step-by-step explanation:

Volume of a sphere is:

$V_{s}=\frac{4}{3}\pi r^{3}$

Volume of a cylinder is:

$V_{c} = \pi r^{2} h$

The volume of the cylinder is 48 cm³.

The cylinder has the same radius (r) and height (2r) as the sphere.

$48 = \pi r^{2} (2r)\\48 = 2\pi r^{3}\\24 = \pi r^{3}$

Therefore, the volume of the sphere is:

$V_{s}=\frac{4}{3} (24)\\V_{s}=32$
