Ivan

The area of the section described above is 1.63cm^{2}. The solution was arrived at by using the knowledge of the area of polygons.

<h3>What is the solution to the above question?</h3>

To solve the above, one would need to first derive the area of the polygon, then derive the area of the inscribed circle.

The area of the circle will not be removed from the area of the polygon to find the area of the silver portion.

Calculate the distance between A(4,3) and B(-1, 6)
elixir [45]

Answer:

Step-by-step explanation:

The formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Where

x2 represents final value of x on the horizontal axis

x1 represents initial value of x on the horizontal axis.

y2 represents final value of y on the vertical axis.

y1 represents initial value of y on the vertical axis.

From the given information,

x2 = - 1

x1 = 4

y2 = 6

y1 = 3

Therefore,

Distance = √(- 1 - 4)² + (6 - 3)²

Distance = √(- 5² + 3²) = √(25 + 9) = √34

Distance = 5.83

1001112 = [ ? ]10<br> ?<br> what number belongs where the question mark is
EleoNora [17]

I suppose you're supposed to convert 100111 from base 2 to base 10. We have

100111_2=2^5+2^2+2^1+2^0=32+4+2+1=39_{10}

so the missing number is 39.
