Algebra.Com's Answer #139670 by feliz1965(151)![]() ![]() ![]() You can put this solution on YOUR website! A = pi(r)^2\r \n" ); document.write( "\n" ); document.write( "If the diameter is 34mm, then the radius is 1/2 of 34.\r \n" ); document.write( "\n" ); document.write( "The radius = 17mm. Now we found the radius, plug it into the formula for area of a circle.\r \n" ); document.write( "\n" ); document.write( "A = pi(17)^2\r \n" ); document.write( "\n" ); document.write( "A = 289pi....This is the exact answer for the area of this circle.\r \n" ); document.write( "\n" ); document.write( "If you want an approximate answer for the area, then we must use 3.14 for pi.\r \n" ); document.write( "\n" ); document.write( "A = 3.14(289)\r \n" ); document.write( "\n" ); document.write( "A = 907.46mm^2 \n" ); document.write( " |
