Problema Solution
Find the circumference of a circle with radius 1.4 in. long. Then use the approximation 3.14 for pi and approximate the circumference.
Answer provided by our tutors
let
r = 1.4 in the radius of the circle
pi = 3.14
C = 2*r*pi the circumference
plug the value for r and pi in the formula for circumference:
C = 2*1.4*3.14
C = 8.792 in
the circumference of the circle is 8.792 in.
