Alborosie
<span>Answer: option B. She did not set the width of the compass to the radius of the circle.

Explanation:

1) If she sets the compass to an arbitrary width to </span><span>draw the arc to cut the circle, the point obtained will not be to the right distance from the first vertex.

2) All the adjacent vertices on a regular polygon have the same distance one from each other.

3) In the hexagon that distance is the same radius, which you can see becasue you can form six equilateral triangles inside the circle, whose side lengths are the radius.

4) So, she should set the width of the compass to the radius of the circle.

A metal conduit will be used as a pathway for wiring through a concrete block. The conduit is a 5 foot long rod with an outer di
kolbaska11 [484]

Answer:  586.59 cubic centimeters .

Step-by-step explanation:

As per given . we have

Inner diameter =  1.8 inches

⇒Inner radius :r = 0.9 in.  (radius is half of diameter)

= 0.9 x (2.54) = 2.286 cm  [∵ 1 in . = 2.54 cm]

Outer diameter = 2 inches

⇒Outer radius : R = 1 inch  = 2.54 cm

Height : h = 5 feet = 5 x(30.48) = 152.4 cm   [∵  1 foot = 30.48 cm]

The formula to find the volume of a hollow cylinder :

V=\pi(R^2-r^2)h , where R= outer radius , r= inner radius and h= height.

Now , the volume of metal in the conduit :

V=(3.14)(( 2.54)^2-(2.286)^2)(152.4)

V=(3.14)(6.4516-5.225796)(152.4)

V=(3.14)(1.225804)(152.4)

V=586.591342944\approx586.59\ cm^3

Hence, the volume of metal in the conduit is 586.59 cubic centimeters .
