document.write( "Question 38056: Please help. I need to find the surface area and volume of a sphere. I have a drawing of a sphere and 34in is written in the middle. Is this the radius or the diameter, can someone help me, I have been working on this problem for weeks. \n" ); document.write( "
Algebra.Com's Answer #23554 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! For a sphere, \n" ); document.write( "V = (4/3)(pi)r^3 \n" ); document.write( "and \n" ); document.write( "A = 4(pi)r^2 \n" ); document.write( "I cannot tell what the 34 in represents since I cannot see the diagram. \n" ); document.write( "I am assuming it is the diameter since you say it is written in the middle of the circle. Thus the radius is half of that or 17 in. Now plug in... \n" ); document.write( "V = (4/3)(pi)(17^3) = 20579.5 cubic in \n" ); document.write( "A = 4(pi)(17^2) = 3631.7 sq in \n" ); document.write( " |
