Rigoletto’s portraits specializes in making circular portraits of people. A large portrait is 42 inches in diameter. A medium portrait is 14 inches in diameter. What is the difference in circumference of the two portraits? Use 3.14 for pi.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The correct answer is -4
