Step 1: Write out the formula

$\begin{gathered} \text{Area of a circle = }\pi r^2 \\ \text{where } \\ r=\text{ the radius of the circle} \end{gathered}$

Step 2: Write out the given values and substitute them into the formula

$r=90m$

Therefore,

$\text{ the area of the circle = }\pi(90)^2=\pi\times8100=8100\pi m^2$

Hence, the area in terms of pi is

$8100\pi$

The last choice is the correct answer

Hi,
If it is f(x)=2x²+3 and not F(x)=2x²+3 then
Answer D.

$f(x)=2x^2+3\\

f(x+1)=2(x+1)^2+3\\
=2(x^2+2x+1)+3\\
=2x^2+4x+5\\
