A Pac-Man poster is the shape of three-fourths of a circle with a diameter of 18 inches and two sides that are 9 inches each. Wh

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>

If Valerie deposited 12,000 into an account threat earns 15% simple annual interest how much money will she have after 3 years

Ad libitum [116K]

Answer:

The amount which she will have into account after 3 years is 17,400 unit

Step-by-step explanation:

Given as :

The principal which is deposited into an account = 12,000 unit

The rate of interest simple annual = 15%

The Time period = 3 years

Let The amount which she have after 3 years = A unit

<u>From simple Interest method</u>

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

Or , Simple Interest = $\frac{12,000\times 15\times 3}{100}$

Or, Simple Interest = $\frac{540,000}{100}$

∴ Simple Interest = 5,400 unit

Now,

Amount = Principal + Simple Interest

Or, A = 12,000 unit + 5,400 unit

∴ A = 17,400 unit

Hence The amount which she will have into account after 3 years is 17,400 unit . Answer
