Use twenty-two sevenths to approximate pi.

Answer 1

43.96
You need to understand the concept of the number pi.

pi is the the number of diameters you can "wrap" around a circle.

The number is 3.14...

So if you had a circle with a diameter of 1 cm then the circumference would be 3.14 x 1 which equals 3.14 cm

Since the diameter is 14 cm the circumference is 3.14 x 14 cm

The equation that deals with this is ...


circumference = pi x diameter

or

c=pi x D
