Question

A right triangle with sides 7 cm and 12 cm forming a right angle is revolved about the 12 cm side. Find the volume of the cone so obtained.​

Answer 1

Answer:

Volume = 616cm³

Step-by-step explanation:

Since right triangle is revolved around the 12cms side, therefore

radius of cone = 7cms (diameter will be 14cm)

height of cone = 12cms

Volume of cone = 1/3$\pi$r²h

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

                           = 616cm³
