Find a function that models the radius r of a circle in terms of its area A.
Solution:
We know that
Circumference of a circle with radius r is 2πr.
Area of circle = πr2
Consider the ratio of area and circumference
A/C = πr2/2πr
By further simplification,
A/C = r/2
We want radius r of a circle in terms of its area A
r = 2A/C
where A is area and C is circumference.
Therefore, the function which models the radius r of a circle in terms of its area A is r = 2A/C.
Find a function that models the radius r of a circle in terms of its area A.
Summary:
The function that models the radius r of a circle in terms of its area A is r = 2A/C.
