In the circus, a lion has been trained to jump through a ring of fire that has a diameter of 8 feet. What is the ring's area?

50.265

Step-by-step explanation:

radius is 4 then you put it in A=Pi r^2

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.

the answer is 21%.
