How do you find the radius from area?

so the area of a circle is=π

r is the radius and π is 3.14

divide both sides by π

a/π=

and if you know the area (a) then divide it by π and use the square root to find r

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
