Problema Solution
A clock tower has a large bell that rings on the hour. A visitor measures the edge of the bell and calculates that it has a circumference of 18.84 yards. What is the edge's radius?
Answer provided by our tutors
let
r = the edge's radius
C = 18.84 yd circumference
C = 2*r*pi
2*r*pi = 18.84
pi = 4.14
2*r*3.14 = 18.84
by solving we find:
r = 3 yd
