) The area of a sector of a circle with diameter 12cm is 6.6cm², if the sector is folded to form a cone,
\n" ); document.write( "Calculate the radius of the base of the cone.
\n" ); document.write( "when folded the radius of sector becomes the slant height of the cone
\n" ); document.write( "The area of sector becomes the lateral surface area of cone\r
\n" ); document.write( "\n" ); document.write( "6.6 = pi*r*6\r
\n" ); document.write( "\n" ); document.write( "r (cone) 6.6/(6*pi)\r
\n" ); document.write( "\n" ); document.write( "= 0.35 cm\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The radius of the base of the cone is approximately 0.35 cm.\r
\n" ); document.write( "\n" ); document.write( "ector of angle 65° is removed to form a thin circular sheet of radius 15cm and folded to form a right circular cone. Calculate the volume of the cone\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
