C. 333.14

Step-by-step explanation:

Both the basketball and baseball has got the shape of a sphere. So that;

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

where r is the radius

i. Volume of the baseball = $\frac{4}{3}$ $\pi$ $r^{3}$

= $\frac{4}{3}$ x $\frac{22}{7}$ x $(9.25)^{3}$

= 3315.5655

volume of the baseball = 3316.57 cube inches

ii. Volume of the basketball = $\frac{4}{3}$ $\pi$ $r^{3}$

= $\frac{4}{3}$ x $\frac{22}{7}$ x $(9.55)^{3}$

= 3649.8372

Volume of the basketball = 3649.84 cube inches

The required difference = volume of basketball - volume of baseball

= 3649.84 - 3316.57

= 333.27 cube inches

The difference of the volumes of the basketball and baseball is 333.27 cube inches.

Step-by-step explanation:

Let's solve your equation step-by-step.

x3+2x2−4=x+2

Step 1: Subtract x+2 from both sides.

x3+2x2−4−(x+2)=x+2−(x+2)

x3+2x2−x−6=0

Step 2: Use cubic formula.

x=1.467504
