A sector of a circle of radius 8cm subtends an angle 90 degrees at the centre of the circle. If the sector is folded without overlap to form the curved surface of a cone, find the base radius, height and volume of the cone taking pie as 22/7
\n" ); document.write( "-------
\n" ); document.write( "Perimeter of the circle 16pi
\n" ); document.write( "----
\n" ); document.write( "Perimeter of the base of the cone:: (3/4)16pi = 12pi
\n" ); document.write( "---
\n" ); document.write( "height of cone::
\n" ); document.write( "radius of base of cone:: 12pi/(2pi) = 6
\n" ); document.write( "h^2 = 8^2 - 6^2 = 64-36 = 28
\n" ); document.write( "h = sqrt(28)
\n" ); document.write( "---------------
\n" ); document.write( "volume of cone:: (1/3)pi*r^2*h = (1/3)pi*36*
