Algebra.Com's Answer #157066 by Alan3354(69443) You can put this solution on YOUR website! Radius of a sphere. The radius of a sphere is given by \n" ); document.write( "the formula \n" ); document.write( "r=(0.75v/pi sign)^1/3 \n" ); document.write( "where V is its volume. Find the radius of a spherical tank \n" ); document.write( "that has a volume of 32pi sign/3 cubic meters. \n" ); document.write( "------------- \n" ); document.write( "I suppose by \"pi sign\" you mean pi. \n" ); document.write( "r=(0.75v/pi)^1/3 \n" ); document.write( "r = (0.75*(32pi/3)/pi)^(1/3) \n" ); document.write( "Sub for v \n" ); document.write( "r = (0.25*32)^(1/3) \n" ); document.write( "r = 8^(1/3) \n" ); document.write( "r = 2 meters \n" ); document.write( " |
