Question

Find the area of the circle in simplest polynomial form. (A = 3.14r2) If the radius of the circle is 2x + 1.

Answer 1

\[A=\pi(2x+1)^2\]

Answer 2

Step by step, like a gee.
(2x+1)(2x+1)=4x^2+4x+1 <--simplest polynomial form
(3.14)(4x^2+4x+1)=1384.74
Area=1384.74 ^_^

Answer 3

\[\pi(4x^2+4x+1)\]
\[4\pi x^2+4\pi x+\pi\]
