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 = 
is the radius of the circle.
Radius is half of perimeter.
Perimeter of the Pac-Man poster = Perimeter of 
circle + 2 sides
Perimeter of the Pac-Man poster = 
+ 9+9 = 42.39+28 = <em>60.39 inches</em>
56/90
" / " means divide
56 divided by 90 = 0.62 with a line over the 2 because it is repeating
The ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
<h3>What is wavelength?</h3>
The wavelength is the distance between two successive troughs or crests. The highest point on the wave is the crest, while the lowest point is the trough.
We have two notes
Number of cycle for blue = 8
Number of cycle for red = 4
Ratio = 8:4 = 2:1
Or
2 to 1
Thus, the ratio of the wavelengths of the two notes is 2:1 option fourth 2 to 1 is correct.
