The length of a diagonal of a square is the side*sqrt(2). Let's call one side of the square: s
So we have 18 = s*sqrt(2)
18/sqrt(2) = s
18sqrt(2)/2 = s
9sqrt(2) = s
Since the perimeter is 4 sides we multiply by 4 to get 36sqrt(2) as the perimeter.

Answer:
Volume of softball is 29 cubic inches.
Step-by-step explanation:
Here we are given that the diameter of a softball is 3.8 inches.
To find the volume of the softball, we must consider the volume of a sphere formula, which is given by:
We also know that radius is half of diameter.
Radius of softball is half of 3.8 which is 1.9 inches.
Plugging this value in the formula, we have
Volume = 28.73 cubic inches.
Rounding to the nearest whole number:
Volume of softball will be 29 cubic inches.
