A square is inscribed In a circle with radius 6<img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B2%7D%20" id="TexFormula1" title="
34kurt

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.

Write the number with the same value as 28 tens
Anvisha [2.4K]
The value of 28 tens is basically doing 28 times 10(in case you didn't know). 28 times 10 is 280. So the value of 280 tens is 280.

You and your friend are shopping for painting supplies. Your friend wants five bottles of paint and one set of paint brushes. Yo
ANTONII [103]
So your friend bought 1 set of brush and 5 bottles of paint
you bought 2 brushes and 7 bottles of paint
1 bottle=3.69
friends cost+your cost=51.69
total you bought 3 brushes and 12 bottles

each bottle is 3.69
12*3.69=44.28
totalcost=51.69=3brushes+12bottles

51.69=3brushes+44.28
minus 44.28 from both sides
7.41=3brushes
divide both sides by 3
2.47=1brush



1 set of paint brushes=$2.47
