Question

The aorta is the largest artery in the human body. In the average adult, the aorta attains a maximum diameter of about 1.18 inches where it adjoins the heart. What is the maximum diameter of the aorta in centimeters? Use the conversion equivalency of 2.54 cm (centimeters) = 1 inch.

Answer 1

Well we know that 1 inch is 2.54 cm.  But how wide is .18?  Lets do .18 x 2.54 to get 0.4572.  Now lets add 2.54 + 0.4572 to get 2.9972.  This means that the maximum width of the aorta is 2.9972 cm.  Hope this helped :)
