irina1246 [14]

Answer:

-1

Step-by-step explanation:

9(x+2)=5−2(x−1)

9x+18=5−2(x−1)

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: $Volume\:of\:sphere=\frac{4}{3}\pi r^3$

Putting value of radius and π and finding volume:

$Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in$

So, Volume of sphere = 4.186 cubic inches
