document.write( "Question 557553: the electric power generated by a windmill varies jointly with the square of the diameter of the area swept out by the blades and the cube of the wind velocity. If a windmill with 6-foot-diameter blades and a 20-mile-per-hour wind generates 10,823 watts, how much power would be generated if the blades were 10 feet in diameter and the wind speed were 12 miles per hour?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i thought that the solution was P(power) = d^2 (diameter)+ v^3 (wind speed), when i substitute in the values given, 10823= (6*2)^2 + 20^3, i came up with 10823=8144, so not the right equation. can anyone offer any help? Thank you!

Hint: If the \"power generated by a windmill varies jointly with the square of the diameter of the area swept out by the blades and the cube of the wind velocity\", then the equation is \"P=kd%5E2v%5E3\" (note: everything is multiplied together) \n" ); document.write( "
