A water balloon shaped like a sphere is filled with water. The water balloon has a diameter of 3 inches. Which measurement is cl
melisa1 [442]

Answer:

Option A. 14.13 cu. in

The volume of the water balloon is 14.13 in³

Step-by-step explanation:

First we calculate the radius

r = 3in / 2

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 1.5in

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (1.5in)³

V = 4.187 * 3.375 in³

V = 14.13 in³

The volume of the water balloon is 14.13 in³

A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo
My name is Ann [436]

if 1 inch is added, you would add 2 inches to to each side of rectangle.  

You would have: W+2, and, L+2,  

Now let W+2 = x and, L+2 = y  

Total area =  x*y=M  

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;  

xy+2x+2y+4=M+52;  

xy=M

2x+2y=48  

x+y=48/2=24  

Now solve :

W+2+ L+2=24  

W+L=20  

The perimeter is 2(W+L)=20*2 = 40 inches.
