volumes of two spheres are 327pi mm cubed and 829pi mm cubed. What is the ratio of their surface areas?\r
\n" ); document.write( "\n" ); document.write( "4/3 *pi^r^3= 327*pi
\n" ); document.write( "r^3= 3*327/4
\n" ); document.write( "r^3=981/4
\n" ); document.write( "r= cuberoot 981/4
\n" ); document.write( "6.26 mm
\n" ); document.write( "surface area = 4*pi*r^2\r
\n" ); document.write( "\n" ); document.write( "4*pi*(6.26)^2
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "4/3 *pi*r^3= 829 *pi\r
\n" ); document.write( "\n" ); document.write( "r^3= 2487/4\r
\n" ); document.write( "\n" ); document.write( "r=8.54 mm\r
\n" ); document.write( "\n" ); document.write( "surface area = 4*pi^(8.54)^2\r
\n" ); document.write( "\n" ); document.write( "Their ratio = 4*pi*(6.26)^2 / 4*pi^(8.54)^2\r
\n" ); document.write( "\n" ); document.write( "Ratio of surface areas = 0.73\r
\n" ); document.write( "
