Answer:
Hey,
so first off we need to know our equation for the area of a circle;
A=πr2
So know we plug in what we already know,
sense the diamiter we can figure out the radius (half way across) by simply dividing 18 units by 2 which is 9.
Now we have
A=π9²
That is your answer π9²
Answer:
The total income of designer from this work is $1649.6.
Step-by-step explanation:
The fees charged by the designer = $1600
The commission on total sales = 8%
