The length of \frac{1}{4} is 2 \frac{7}{16} feet.

To figure this out all we have to do is change 9\frac{3}{4} to a decimal, which would be 9.75. Since we are looking for \frac{1}{4} of our original number, we can just divide it by 4 to find our answer.

In decimal form we get 2.4375, which is equal to 

2\frac{7}{16} in mixed number form or 

\frac{39}{16} in exact form.

Although I think the answer you are looking for is in mixed number form: 2\frac{7}{16}

Thank you for the question! I hope this helped! Have an amazing day :D

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 .
