Easy question! chemistry - ! i give - it's the picture! - question 3

The leaning tower of pisa is cylindrical and as such the volume can be approximated using the same formula as a regular cylinder.

Volume of a cylinder (V) = 

Assume  = 
    V = 9891 
    h = 56 m 

Let: Radius= r
       Diameter= D 
Then D= 2r

By substituting the known values into the equation and transposing one can formulate an equation to solve for D.
V = 
: . 9891 = 

Making r the subject of this equation:
 
 

Since the Diameter is 2r then multiply both sides of the equation by 2
: . 
thus     D =  

Part B:

Since the formula for Diameter has be formulated, substitute the values of the variables and solve for D
    D = 
: . D = 
        = 2 * 7.497m
        =  14.993 m  

Part C:
Therefore it can be concluded that the Diameter of the base of the Leaning Tower of Pisa is approximately 14.99 meters.

 

You would do 1500/4 and the answer is 375
