PLEASE DO $7,8$ AND $9!($aswell as the other ones$)$ Objective: Write MATLAB code to use a Monte Carlo technique to find the area of the following circle

You can do this as follows

Generate two random number between $-0\mathrm{.}5$ and $0\mathrm{.}5$ ; call them $x$ and $y.$ This is the coordinate of a point within the box $($of side length, $L=1).$

Determine if this random number is inside the circle of diameter, $L=1.$ Hint: remember the equation for points on a circle $,$ where $r=$ radius
