Find the volume of the sphere shown to the right. Give an answer in terms of pi and rounded to the nearest cubic unit.

Vladimir [108]

The correct answers are:
Exact volume = $V = \frac{32}{3} \pi$ in^3
Approximate volume = V = 33.51 in^3

Explanation:

The volume of the sphere is: $V = \frac{4}{3} \pi r^3$

Since r = 2 in

Hence
$V = \frac{4}{3} \pi (2)^3 \\ V = \frac{32}{3} \pi$ in^3 (exact)
V = 33.51 in^3 (approximate)

A number plus itself, plus twice itself, plus 4 times itself is equal to -104

NARA [144]

The scenario will will be represented by: $x+x+2x+4x=-104$

The number will be -13

Step-by-step explanation:

We have to convert the given situation into the mathematical form

Let x be the number

Then

"a number plus itself"

x+x

"plus twice itself"

x+x+2x

"plus 4 times itself"

x+x+2x+4x

"is equal to -104"

$x+x+2x+4x=-104$

This can also be written as:

$x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13$
