Jasmine needs to sew fringes on a circle pillow with a radius of 5 inches. How many inches of fringe does she need to buy?
Answer provided by our tutors
We need to find circumference of circle with radius r = 5 in.
The formula for circumference of circle is:
C = 2*r*π, where r is the radius and π = 3.14
C = 2*5*π
C = 10π
C = 10*3.14 in
C = 31.4 in
Jasmine needs to by 31.4 inches of fringe.
