The diameter of a standard basketball is 9.5 inches. if the basketballs are covered in rubber, what is the minimum amount of rubber needed to manufacture a set of four basketballs

1134.11495in^2

Step-by-step explanation:

SA=4x(pi)x(r)^2

4(pi)(4.75)^2=283.528737

283.528737x4(because there's four basketballs) =1134.11495

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
