Question

Identify the diameter of ⨀Q, given that A = 169π in². Please Give the Explanation and the Answer.

Answer 1

There's a formula for the area of a circle. You should look it up in your textbook (or other learning material). It's A = πr² .

That, along with the fact that the diameter of a circle is equal to twice its radius, is all you need to solve this problem.

Answer 2

Area of a circle is r^2pi.

area=169pi; so r^2=169; r=13.dia=26.
