Question

Tom and Germany have a circular pool with a diameter of 12 ft what is the circumference of the pool use 3.14 for π

Answer 1

The circumference of a circle is given by the formula:

$C\text{ = }\pi\cdot\text{ D}$

That is the number pi (3.141592....) times the diameter. Then, we have (for pi = 3.14):

$C\text{ = 3.14 }\cdot\text{ 12 ft = 37.68 ft}$

The circumference is 37.68ft.
