PLEASE HELP ASAPPP A cylinder shaped water tank has a height of 212 ft (6461.76 cm), and is able
to hold 15,000 gallons of water (15,000,000 mL or 15,000,000 cm3). The
volume of a cylinder is expressed by the equation
V = tr^2h
Where V is the volume, r is the radius, and h is the height of the cylinder.
Express the radius (r) in terms of volume (V) and height (h), then determine
the radius of a cylinder water tank (in centimeters) that is filled to capacity.

 r =  

27.2cm

Explanation:

Given parameters:

Height of tank  = 6461.76cm

Volume of water  = 15000000cm³

Volume of cylinder  = r² h

i. Express radius in terms of volume;

  we are to make radius the subject of the expression;

              v = r² h  

     divide both sides by πh

            =  

              r²   =  

              r =  

ii.

Radius of the water tank;

             r  =   = 27.2cm

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
