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

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
