It costs ₹ 2200 to paint the inner curved surface of a vessel 10cm deep. it rhe cost of painting is at the rate of ₹20 per m2 ,find the first radius of the base second inner curved surface area of the vessel and third capacity of the vessel. is any related questions

H= 10m
1)   inner curverd surface area = total cost / cost of painting per m^2
  2200 /20 m^2    =     110 m^2 
2)  2 pie  rh = 110 
    2 *  22/7  * r   *   10   = 110
    r =    110 *   7   / 2 * 22  * 10      =>  1.75 m is radius 
3)  capacity of vessel =   pie r^2 h 
     22/7   *  1.75 * 1.75 *  10     =>    96.25 m ^3

so   inner curveed surface area =  110m^2 
    radius   = 1.75 m   and capacity = 96.25 m ^3   {   1m^3 = 1kl }
                                                           96.25 kl

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
