How do you find the area of diameter of a circle? - Answers

You misunderstand. 'The area of the diameter'. The diameter is a STRAIGHT LINE, it is NOT an area. The question should read ' How do you find the area of a circle, knowing only the diameter?' To answer the question Remember the equation ;- A = pi*r^2 Where 'A' is the area 'pi' ~ 3.14 (A constant) 'r' is the radius. Now the radius is one half the diameter ; (r = d/2) or (d = 2r) We can algebraically substitute A = pi *(d/2)^2 So as an example , is the diameter is 20 Then A = 3.14 ( 20/2)^2 (Remember ; do what's inside the brackets first) A = 3.14 * 10^2 A = 3.14 * 100 A = 314.00
