What is the volume of a sphere with a radius of 6in? Round to the nearest hundredth. Remember V = 4/3πr3 * 20 points 457.86 inch

kakasveta [241]

Given:

The radius of the sphere is 6 in.

To find:

The volume of the sphere.

Solution:

We know that, the volume of a sphere is

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

Where, r is the radius of the sphere.

Putting r=6, we get

$V=\dfrac{4}{3}\pi (6)^3$

$V=\dfrac{4}{3}\pi (216)$

$V=288\pi$

$V\approx 904.78$

The volume of the sphere is 904.78 inches cubed.

Therefore, the correct option is C.

Which graph shows the line y - 2 = 2(x + 2)?

klasskru [66]

For this case we have the following linear function:
$y - 2 = 2 (x + 2)
$
Rewriting we have:
$y - 2 = 2x + 4

y = 2x + 4 + 2

y = 2x + 6$
We observe that the linear function has:
Positive slope and equal to 2.
Intersection with the axis y equal to 6.
Answer:
y = 2x + 6
