An instrument shows the number of revolutions per minute made by each tire of a car. In each revolution, the car travels a distance equal to the circumference of one of its tires. The circumference of each tire is equal to 2πr, where r is the radius of the tire.\r

The radius of each of her old tires is 0.30 meter, and the radius of each of her new tires is 11% larger than the radius of one of her old tires. What is the circumference of each new tire, to the nearest tenth of a meter?
\n" ); document.write( "======================
\n" ); document.write( "r of new tires = 0.3*1.11 = 0.333 meters
\n" ); document.write( "C = 2*pi*r \n" ); document.write( "
