Since it is a square that means each side is equal.
The perimeter is 24, and since there is four sides we would divide it by four to find the length of each side.

24/4 = 6

Each side is 6.
By looking at the picture, one side of the square, is the length of the radius.

The radius of the square is 6.

The only thing left to do is to find the circumference.
The circumference formulas are:

C = \pid
C = 2\pir

We can use the first one Diameter x pi (3.14)
To find the diameter we would just multiply the radius by two.

6 x 2 = 12

Diameter = 12

So multiply it by pi

12 x 3.14 = 37.68
or D 12\pi

slava [35]

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 = 2\pi r

r is the radius of the circle.

Radius is half of perimeter.

r=\dfrac{18}{2} = 9\ inches

Perimeter of the Pac-Man poster = Perimeter of \frac{3}{4} circle + 2 sides

Perimeter of the Pac-Man poster = \frac{3}{4}\times 2\times \pi \times 9  + 9+9 = 42.39+28 = <em>60.39 inches</em>
