Find the area of this semi-circle with diameter, d
= 55cm.
Give your answer rounded to 2 DP.

- (2, -7)

- lines r and s and lines t and u must be parallel

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
