A circle is inscribed in a square is 10 inch sides what is the circumference of the circle use 3.14 as an approximation for pie
MissTica

Answer:

31.4 inches

Step-by-step explanation:

If a circle is inscribed in a square then diameter of circle inscribed is same as  side as of square.

In the given problem it is given that side of square is 10 inches.

So diameter of  circle inscribed is 10 inches

we know radius of circle is half of  diameter of  circle

Thus, radius of circle inscribed = diameter of  circle/2 = 10/2 = 5inches.

Expression to calculate circumference of circle is given by 2\pi r

where r is the radius of circle.

Thus circumference of  circle inscribed is

2*\pi *5\\=> 10*3.14 \\=> 31.4

Thus, circumference of  circle inscribed is  31.4 inches

The area of the regular hexagon is 10.4 in.2. a regular hexagon has side lengths of 2 inches and an area of 10.4 inches squared.
VARVARA [1.3K]

Answer:

  (b)  1.7 in

Step-by-step explanation:

The area of a regular polygon in terms of perimeter and apothem is given by the formula ...

   A = 1/2Pa

For a hexagon, the perimeter is 6 times the side length, so this becomes ...

  A = 1/2(6s)a = 3sa . . . . . for side length 's' and apothem 'a'

__

Solving for the apothem, we find ...

  a = A/(3s)

For the given values of area and side length the apothem is ...

  a = 10.4/(3·2) = 1.733... ≈ 1.7 . . . inches

The apothem, rounded to tenths, is 1.7 inches.

Digiron [165]
Basically, it is not a function because 1 domain (in this case, 5) can not be connected to two different ranges(1 and -2). Each domain must only connect to one range.
