Becca wants to make a giant cherry pie to try to break the world record. if she succeeds in making a pie with a 20 foot diameter, what will be the total distance around the pie?

the total distance around the pie is the circumference of the pie, assuming that the pie is a perfect circle then the formula for the circumference of a circle is:
c = piD
where pi is equal to 3.1416
D is the diameter of pie or circle

substitute the given values
C = (3.1416) ( 20 ft
c = 62.832 ft

31 is prime. and it’s prime factorization is just 31.
