Enclosed by 50 feet of rope. determine the diameter?

Question

A circular region is enclosed by 50 feet of rope. How can you best determine the diameter of the region?

Answer 1

if circumference is 50 ft of rope in circular shape, use C = pi•diameter; thus diameter = 50/pi.

use pi = about 3.1416

Answer 2

the circumference is 50 ft

c = 2πr = πd

50 = πd

d = 50/π feet

 

Either use the pi button on your calculator or

3.14 as pi to do the division.
