Question

angle triangle having sides 21cm 28cm 28cm and 35cm if we take the sides of 28 cm ashok axis and rotate the triangle around it then write the name of the shape obtained and calculate its volume


please explain in brief and also attach your answer..​

Answer 1

Answer:

Right circular cone

V = 12936 cm³

Step-by-step explanation:

If we rotate the triangle around 28cm axis then,

a right circular cone is formed with

height= 28cm

radius= 21cm

slant height= 35cm (not needed in volume formula)

Volume of cone =1/3πr²h

                            = 1/3 x 22/7 x 21 x 21 x 28

                             (cancel out)

                            = 22x 21x 28

                            = 12936cm³

Hope it helps.
