what is the circumference of 7.8 centimeters by 5.5 centimeters by 7. 3 centimeters in size between that and 3.5 centimeters

Aug 23rd, 2014

What you are asking is the difference of circumference of a circle circumscribing  a rectangle of 7.8 x 5.5 and a circle circumscribing a rectangle of 7.3 x 3.5

The bigger circle has a diameter 9.544 cm

The smaller circle has a diameter  8.096 cm

Difference in circumference =pi *(9.544-8.096) = pi (1.448) cm = 3.14 *1.448 =4. 548 cm

or more exact value = 4.550 cm

Up to two decimal it is 4.55 cm

Answer: 4.55 cm
