Tom and Jerry each order a pizza. The circumference of Tom’s pizza is 30% greater than the cir-cumference of Jerry’s pizza. The area of Tom’s pizza is what percentage greater than the area of Jerry’s ?
\n" ); document.write( "(A)30% (B) 49% (C) 50% (D) 69% (E) 75%
\n" ); document.write( "----------------------
\n" ); document.write( "Circumference and radius are directly related, so the radius is 1.3 times.
\n" ); document.write( "Area is a function of the square of the radius, so it's 1.69 times (1.3*1.3).
\n" ); document.write( "That's 69% greater.
