What is the area and circumference of a circle with diameter 22 mm?\r \n" ); document.write( "\n" ); document.write( "The area of a circle is pi times the radius squared, and the circumference \n" ); document.write( "is pi times the diameter. Pi is the irrational number equal to approximately \n" ); document.write( "3.14. The radius is half the diameter because it is the distance from the edge \n" ); document.write( "of the circle to the center point of the circle. So the radius is \n" ); document.write( "22/2=11 mm. The area is pi times r^2=3.14*(11 mm)^2=379.94 mm^2. The circumference is pi*d=3.14*22mm=69.08 mm. \n" ); document.write( " |
