A cylindrical hockey puck is 1 inch thick and has a diameter of 3 inches. What is volume of the puck?

 

a 3pi in^3

b 6.75pi in^3

c 9.5pi in^3

d 12pi in^3

 

 

 

I don't know if i'm doing something wrong, but got 5 for this, but it's not one of my answer choices

The volume of the puck  =

 

pi * (diameter / 2)^2 * thickness of puck

 

So...we have

 

pi * ( 3 / 2)^2  * 1  =

 

pi * ( 9 /4) * 1  =

 

(9/4) pi   =

 

2.25pi  in^3

 

[ None of the choices are correct...]

And what formula did you used, I used the cylinder formula

The volume of a cylinder is given by :

 

pi * ( radius)^2 * height  =  pi * (diameter / 2) ^2 * height

 

Note....the thickness of the puck  = height of a cylinder....
