Answer:
The volume and the curved surface area of the solid formed is 
and 
respectively.
Step-by-step explanation:
Given that,
A right triangle with sides 6 cm, 8 cm and 10 cm is revolved about the side 8 cm.
As the triangle is revolved at 8 cm it forms a cone of height 8 cm and radius 6cm.
Height, h = 8 cm
Radius, r = 6 cm
The volume of the solid formed is given by :
The curved surface of the solid formed is :
l is slant height
Hence, the volume and the curved surface area of the solid formed is and respectively.

Answer:
No, we can't make 20 by adding 5 odd numbers.
Step-by-step explanation:
An odd number is represented by 2n+1, the sum which we got is represented in this form, so it's obviously an odd number. But 20 is an even number, so sum can't be 20.
