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>

84

Step-by-step explanation:

This question is solved using proportions.

From the sample:

11 + 3 = 14 out of 13 + 11 + 3 = 27 would rate the test something other than easy.

Out of 162:

Applying the rule of three:

14 - 27

x - 162

Applying cross multiplication:

27x = 14*162

x = \frac{14*162}{27}

x = 84

Thus the correct answer is given by option C.
