Answer:
When the diameter is given you just take half of it so simply put what is half of 16pi and it will give your answer. :)
Step-by-step explanation:
Area=Length x Width (A=LW)
A=30.5 x 12.5
A=381.25
So based on your question where there is a rectangle inscribed in a semicircle or a radius 10 as shown in your figure. The possible function that could represent the are of the rectangle is A=2x*sqrt(100-x^2) i hope you are satisfied with my answer and feel free to ask for more

Then multiply 300*0.45
You get 135
