Respuesta :
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,
[tex]Perimeter, P = 2\pi r[/tex]......................(1)
Where, r - Radius of circle
From the given,
r = 4.75 inches
Equation (1) becomes,
[tex]P = 2 (\pi )(4.75)[/tex]
[tex]= 2(3.14)(4.75)[/tex] (∵ [tex]\pi[/tex]= 3.14)
[tex]=2(14.915)[/tex]
[tex]=29.83[/tex]
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.
