Question

A cylindrical Jar of diameter 24 CM is filled with water .And number of solid identical cones of base radius 4 cm and hight 3 cm are completely immerged in the Jar sides upwards 7 cm. the number of cones is

Answer 1

Answer:

Number of cones=21

Step-by-step explanation:

Volume of the cylinder = π×r²×h

Where r is the radius r= 12cm

h= 7cm

Volume of cylinder = π×12²×7= 3165.12cm³

Volume of cone= π×r²×h÷3

For cone radius r =4m height h=3cm

Volume of cone = π×4²×3=150.72

Number of cones= volume of cylinder÷ volume of cones

                              =21
