Answer:
60.39 inches
Step-by-step explanation:
Given that:
A Pac-Man poster which is having three fourth of a circle and there are two sides.
Diameter of circle = 18 inches
Sides of Pac-Man poster = 9 inches
To find:
Perimeter of the Pac-Man poster.
Solution:
Perimeter of a figure is nothing but equal to the periphery i.e. the outer area of the circle/figure.
Perimeter of a circle is given by the formula:
Perimeter = [tex]2\pi r[/tex]
[tex]r[/tex] is the radius of the circle.
Radius is half of perimeter.
[tex]r=\dfrac{18}{2} = 9\ inches[/tex]
Perimeter of the Pac-Man poster = Perimeter of [tex]\frac{3}{4}[/tex] circle + 2 sides
Perimeter of the Pac-Man poster = [tex]\frac{3}{4}\times 2\times \pi \times 9[/tex] + 9+9 = 42.39+28 = 60.39 inches
