Answer:

48 in

Step-by-step explanation:

The diagonal of the inscribed square equals the diameter of the circle.

1. Calculate the diagonal of the square

d = 2r = 2 × 6√2 in =12√2 in

2. Calculate the side of the square

∆ACB is an isosceles right triangle.

We can use Pythagoras' Theorem to calculate the length of a side s.

\begin{array}{rcl}s^{2} + s^{2} & = & (12\sqrt{2})^{2}\\2s^{2} & = & 144 \times 2\\s^{2} & = & 144\\s & = & \text{12 in}\\\end{array}

3. Calculate the perimeter of the square

P = 4s = 4 × 12 in = 48 in

The perimeter of the square is 48 in.

HELP ME PLEASE!! ASAP!!
Levart [38]
The total area is given by:
 A1 = (300) * (500)
 A1 = 150000 feet ^ 2
 The area occupied by 5 people is:
 A2 = (5) * (5)
 A2 = 25 feet ^ 2
 Then, we can make the following rule of three:
 5 --------> 25
 x --------> 150000
 Clearing x we have:
 x = (150000/25) * (5)
 x = 30000

What is the value of x?<br> Enter your answer in the box.<br> units
sineoko [7]

Answer:

x = 28

Step-by-step explanation:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

Then x/(x +10) = 42/(42 +15)

x(57) = 42(x + 10)

57x = 42x + 420

15x = 420

x = 28
