A circular gift has a 4.75 inch radius. alyssa wants to wrap a ribbon that costs $0.50 per inch around the gift. How much money
Montano1993 [528]

The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.

Step-by-step explanation:

The given is,

                      A circular gift has a 4.75 inch radius

                      Ribbon that costs $0.50 per inch

Step:1

           Formula to calculate the perimeter of circle,

                               Perimeter, P = 2\pi r......................(1)

           Where, r - Radius of circle

           From the given,

                                                  r = 4.75 inches

          Equation (1) becomes,

                                                P = 2 (\pi )(4.75)

                                                    = 2(3.14)(4.75)            (∵ \pi= 3.14)

                                                    =2(14.915)

                                                    =29.83

                              Perimeter, P = 29.83 inches

Step:2

            Cost for wrap the ribbon to around the circular gift,

                                          = Perimeter of circular gift × ribbon cost per inch

                                          = (29.83 × 0.50)

                                          = $14.915

          Cost for wrap the ribbon to around the circular gift = $14.915      

Result:

           The Alyssa will spend $14.915 for wrap a ribbon around the gift, if a ribbon costs $0.50 per inch.
