What is the circumference of a circular swimming pool with a diameter of 6 ½ feet? (use 22 over 7 as pi)

trapecia [35]

Answer:

10.21 feet.

Step-by-step explanation:

circumference of circle with diameter d is given by $\pi d$

where r is the radius of the circle.

_____________________________

given

diameter = 6 1/2 = 13/2 feet

\thus, circumference of circle is calculated as following

$circumference = \pi *13/2 = 22/7 * 13/2\\circumference = 11*13/7*2 = 143/14 = 10.21$

Thus, circumference of given circle is 10.21 feet.
