Problema Solution
A circular quilt is made from 113.04 square feet of fabric. How much trim is needed to go around its edge? Use 3.14 for pi.
Answer provided by our tutors
Let
r = the radius of the circular quilt, r>0
pi = 3.14
A = 113.04 the area of the circular quilt
We need to find the circumference C of the circular quilt, but in order to do that, first we have to find the radius:
A = r^2*pi
r^2*3.14 = 113.04

r = 6 ft
C = 2*r*pi
C = 2*6*3.14
C = 37.68 ft
37.68 ft of trim is needed.
