Find the Circumference of the circle below. Round to the nearest tenth. Use 3.14 for 7T
21 mi
The circumference of the circle is
65.9
131.9
131.88

circumference = π2r = (3.14)(2)(21) = 131.88 miles

Step-by-step explanation:

john earns $14.00 for two hours of work.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
