Question

7. In
A ABC,
angleB = 90°, AB = 6.3 cm
and
BC = 8.4 cm. It is revolved about the side
AB. Find the volume of the cone so obtained.
Similarly the triangle ABC is revolved about
the side BC, then find the volume of the
cone so obtained.​

Answer 1

Answer:

In triangle ABC. B = 90°. AB = 6.3 cm and

BC = 8.4 cm. It is revolved about the sideAB. Find the volume of the cone so obtained.Similarly the triangle ABC is revolved aboutthe side BC. then find the volume of the cone so obtained

Answer 2

Step-by-step explanation:

cone volume:- 1/3 pi*r2*h

= 1/3 *22/7*6.3*6.3*8.4

= 349.272 cm3

cone volume:- 1/3 pi*r2*h

= 1/3 *22/7*8.4*8.4*6.4

= 465.696 cm3
