Answer:

Step-by-step explanation:

w + 1/2 ➡ (2w + 1)/2

w/4 + 2➡ (w + 8)/4

(2w + 1)/2 = (w + 8)/4

8w + 4 = 2w + 16 ➡ 6w = 12

w = 2

Baseballs and softballs com in different sizes for different leagues. If the diameter of a baseball is 3 inches and a softball i

Vanyuwa [196]

Answer:

Step-by-step explanation:

Alright, lets get started.

Diameter of baseball is given as 3 inches.

Hence the radius of baseball will be : $\frac{3}{2}=1.5$

Hence the volume of baseball is : $\frac{4}{3}\pir^3$

Hence the volume of baseball is : $\frac{4}{3}\pi1.5^3$

Hence the volume of baseball is : 14.13 inches cube

Now, diameter of softball is given as 3.8 inches.

Hence the radius of softball will be : $\frac{3.8}{2}=1.9$

Hence the volume of baseball is : $\frac{4}{3}\pir^3$

Hence the volume of baseball is : $\frac{4}{3}\pi1.9^3$

Hence the volume of baseball is : 28.72 inches cube

Hence the difference of volumes will be: $28.72-14.13$

Hence the difference of volumes will be 14.59 or 14.6 inches cube

So the answer is 14.6 inches cube. : Answer

Hope it will help :)
