Answer:
The radius of the volleyball is 8.3 inches
Step-by-step explanation:
Given


Required
Determine the value of r
To do this, we simply substitute 288 for v and 3.14 for π in the given equation.
This gives





(Approximated)
Hence;
<em>The radius of the volleyball is 8.3 inches</em>
Answer:
Part 1) 
Part 2)
a) 
b) 
c) 
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
Part 1) Write an expression for the perimeter of the shape
we know that
The figure is composed by a larger square, a rectangle and a smaller square
1) The area of the larger square is given

so
The length and the width of the larger square is x units
2) The area of the rectangle is given

so
The length of the rectangle is x units and the width is 1 unit
3) The length and the width of the smaller square is x units
see the attached figure N 2 to better understand the problem
Find out the perimeter
The perimeter is the sum of all the sides.
so


Part 2) Find the perimeter for each of the given values of x.
a) For x=7 units
Substitute the value of x in the expression of the perimeter

b) For x=5.5 units
Substitute the value of x in the expression of the perimeter

b) For x=7/3 units
Substitute the value of x in the expression of the perimeter

To find the length of the side, will take the under root of the area. So, the side will be :
c) 24.4 cm
There are 20 nickles in one dollar, so 20(nickles in a dollar) x 50(dollars) = 1,000
Hope this helps!
