The circumference of a circle varies directly as the diameter. A circular pizza pie with a diameter of 1 foot has a circumference of 3.14 feet. What will be the circumference of a pizza pie with a diameter of 1.5 feet?
Thank you all for the help i really appreciate it.
As you stated the proportion of diameter and radius of circles is a constant:Originally Posted by Ravangerz
. (Even though the question refers to pizze this constant number is definitely not pie but pi
)
Now use the proportion:
Solve for c (= circumference)
