Question

A Right angled triangle having perpendicular sides of 12 cm and 5 cm is rotated about its hypotenuse. For the solid thus generated , find the volume of the solid (Double cone)?

The correct answer is: 314.15cm


    Hint:
    • The volume of the cone is 1 third pi r squared h
    Explanation:
    • We have given a Right angled triangle having perpendicular sides of 12 cm and 5 cm is rotated about its hypotenuse.
    • We have to find the volume of the solid
    Step 1 of 1:
    When we rotate the right angle triangle around hypotenuse we will get a cone with height  and the radius
    So, The Volume will be
    V equals 1 third pi r squared h
    equals 1 third pi left parenthesis 5 right parenthesis squared cross times 12
    equals 314.15 cm cubed
