Question

How do I find the area of a circle?

Answer 1

if the R is radius of the circle, the area is \[\pi(R/2)^{2}\]

Answer 2

Thanks!

Answer 3

ur welcome.

Answer 4

Nope, where \(r\) is the radius of a circle, the area is \(\pi r^2\).

Answer 5

If \(d\) is the diameter, then \(r=d/2\) so the area in terms of \(d\) is \(\pi (d/2)^2\).

Answer 6

Sounds about right. Unfortunately, I have failed the question. But it's okay.
