( 16) Which fertilizer produce acidity in soil A.Ammonium sulfate B.Sodium nitrate C.Calcium ammonium nitrate D.Calcium nitrate​

Answer:

385cm^3

Step-by-step explanation:

Volume of cone = (1/3)πr^2h

                            = 1/3 * 22/7 * 7 * 7 * 12

                            = 616cm^3

Volume of Cylinder = πr^2h

                                  = 22/7 * 7/2 * 7/2 * 6

                                  = 231cm^3

Therefore,

Remaining = Volume of cone - Volume of cylinder

                   = 616 - 231

                   = 385cm^3

Answer:

Remaining piece of wood 385 cm³

Step-by-step explanation:        

Given data

A cylinder is drilled out from a wooden cone

The radius and height of the cylinder is equals to half that of the cone

Dimensions of cone are

⇒ Radius OP = 7 cm , ⇒  Height OQ = 12 cm  

⇒ then volume of cone = [tex]\frac{1}{3} \pi r^{2} h[/tex] =  [tex]\frac{1}{3}[/tex] × [tex]\frac{22}{7}[/tex] × 7 × 7 ×12 =

                                                    = 22 × 7 × 4 = 616 cm³

Dimensions of cylinder are  

⇒ half of that of the cone

⇒ radius of cylinder r = 7/2 = 3.5 cm    

⇒ height of cylinder h = 12/2 = 6 cm

⇒ volume of the cylinder =  [tex]\pi r^{2} h[/tex] = [tex]\frac{22}{7}[/tex] × 3.5 × 3.5 × 6

                                                      = 22 × 3.5 × 3 = 231 cm³  

here we need to find the remaining piece of wood

⇒ Remaining piece of wood = volume of cone - volume of cylinder

                                                = 616 cm³  -  231 cm³    

                                               = 385 cm³
