Find the area of a semi circle with diameter d cm

Step-by-step explanation:

Semicircle is HALF of a circle. The area of a circle is given by:

So, area of semi circle is:

Where r is the radius (half of diameter).

The diameter is given as "d", so the radius is half of that, this would be:

Now, substituting this into "r", we get the expression for area of the semicircle:

Area =

This is the area.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
