Formula is pie radius-squared
Radius= 1/2 of diameter
Radius = 7
Formula = pie- 7 squared
Or as the question says
Pie= 3.14
3.14 multiply by 7 squared
= (A) 153.86 yards squared

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>

a local hamburger shop sold a combined total of 456 hamburgers and cheeseburgers. The number of cheeseburgers sold was three tim

Ganezh [65]

H + c = 456
c = 3h

h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold

c = 3h
c = 3(114)
c = 342......cheeseburgers sold
